AIRCRAFT ACCIDENT REPORT

Adopted: March 24, 1976

AIRLIFT INTERNATIONAL, INC. McDONNELL-DOUGLAS DC-8-63F, N6161A JOHN F. KENNEDY INTERNATIONAL AIRPORT JAMAICA, NEW YORK SEPTEMBER 20, 1975

SYNOPSIS

About C355 e.d.t. on September 20, 1975, Airlift International, Inc., Flight 101, a McDonnell-Douglas DC-8-63F, struck components of the runway 22L instrument landing system, the runway 4R automatic landing system flasher, and the runway 4R field monitor while taking off from runway 22L at the John F. Kennedy International Airport at Jamaica, New York. The accident occurred during the hours of darkness and reduced visibility. The takeoff was made on an 8,400-foot runway using calculations for a takeoff on a 11,352-foot runway.

The four occupants aboard were not injured. The aircraft was damaged slightly and several navigation aid ground components were destroyed.

The National Transportation Safety Board determines that the probable cause of this accident was the certain's decision to use a runway that was too short for the aircraft's takeoff performance capability under existing loa, and weather conditions. As a result, the aircraft struck obstacles beyond the departure end of the runway before it began to climb. The flightcrew had failed to use available data which would have informed them that the runway was not long enough for the takeoff.

1. INVESTIGATION

1.1 History of the Flight

On September 20, 1975, Airlift International, Inc., Flight 101, a McDonnell-Douglas DC-8-63F, N6161A, was being operated as a scheduled cargo flight from the John F. Kennedy International Airport (JFK) to the San Francisco International Airport (SFO).

Before departing, the captain checked the flight plan and weather and accepted the weight and balance calculations that had been

Flight 101 changed from the ground control frequency to towecontrol frequency and was cleared for takeoff on runway 22L. The first officer made the takeoff from a standing start, using the same V speed values that had been computed for runway 22R (V1 146 kn.; VR 153 kn.; and V2 164 kn.). The precise takeoff starting point on the runway could not be determined.

The aircraft lifted off near the end of the runway and the landing gear struck several fixed structures associated with the navigational aids beyond the runway which were less than 5 feet above the runway elevation.

The captain and first officer did not recall anything that the aircraft struck, but the flight engineer recalled that he felt and heard some "thumps" after liftoff.

After the aircraft had reached an altitude of 5,000 feet, the flight engineer reported to the captain that the aircraft was not pressurizing. The crew reported their difficulties to the New York Air Route Traffic Control Center when the aircraft reached 16,000 feet.

The flight changed its destination to Atlanta, Georgia, and was cleared by New York ARTCC to maintain 16,000 feet. Later on, company personnel advised the flight to divert to Miami. The flight arrived before daylight and held to the west. After it became light, the flight made a low approach and flew by the Miami Tower with landing gear extended. Tower controllers told the flightcrew that one Inboard landing gear tire was flat on each of the main gears. The flight proceeded to a fuel dump area where all excess fuel was dumpeu to lower the landing weight.

The approach and landing at Miami International Airport (MIA) to runway 9R was routine, except that additional fires blew out during the landing.

1.2 Injuries to Persons

1.3 Damage to Aircraft

Main landing gear tires Nos. 1: 2, 3, 4, 5, and 6 were either damaged c: destroyed. A 4-1inch by 6-1inch skin depression and puncture was located at the lower inboard right wing, 2 feet outboard of the fuselage station and bordering the landing gear cutout X. Orange marks

and a skin depression were found on the lower right fuselage skin, between station 1220 and 1292. The fuselage skin adjacent to the aft rear baggage compartment door at fuselage station 1385 was torn. A 4-inch by 6-inch gouge was located in the aft rear baggage compartment door's exterior skin, near stations 1420 to 1424. The cabin pressure outflow butterfly valve hinge was damaged at station 1640. The circumferential fairing around the butterfly valve door, near stations 1630 to 1645, was torn. The lower edge of the butterfly valve was scored and dented. The fuselage tail skid fairing and associated metal were crushed and torn near station 1766. The right-hand fuselage skin near station 1805 was punctured and contained a 3-inch by 4-inch tear. The right horizontal stabilizer's leading edge (station 76.500) had a skin depression and a 4-inch by 4-inch puncture. The lower skin on the right horizontal stabilizer, near the spar and station X7S 145.500 had a 3-inch by 5-inch skin puncture.

1.4 Other Damage

At JFK, the red approach lights for runway 4R, located 250 feet from the end of the runway and 1 foot above the elevation of the runway, were destroyed. The instrument landing system (ILS) monitor locations 1 and 2, located 325 feet from the end of the runway and 2.75 feet above the elevation of the runway, were destroyed. A section of the railing on the landing light pier, located between 625 and 750 feet from the end of the runway and 4.5 feet above the elevation of runway 4R, was destroyed. The instrument landing system's localizer antenna system, located 500 feet from the end of the runway and 4.5 feet above the elevation of the runway, was destroyed. An approach light and stanchion, located 650 feet beyond the end of the runway and 4.5 feet above the elevation of the runway, were destroyed. Ar. approach light and stanchion, located 850 feet beyond the end of the runway and 4.5 feet above the elevation of the runway, were destroyed.

1.5 Crew Information

The three crewmembers were properly certified for the flight. (See Appendix B.)

1.6 Aircraft Information

The aircraft was certified, equipped, and maintained in accordance with Federal Aviation Administration (FAA) requirements. (See Appendix C.) The center of gravity was within the prescribed limits. The aircraft's gross weight was less than the maximum allowable limit.

1.7 Meteorological Information

The JFK 0351 surface weather observation was, in part, as follows:

Record special observation, ceiling -- indefinite zero, sky obscured, visibility -- 1/8 mile, fog, temperature -- 68°F, dew point -- 68°F, wind -- 140° at 3 kn, altimeter setting -- 30.00 in., 10-minute extreme values of RVR for runway 4 right were 1,600 feet lowest value and 1,800 feet highest value.

The air traffic control specialist reported the visibility as 1/16 mile at the actual departure time of Flight 101.

The official surface weather observations taken during the 2 hours before takeoff showed that prevailing visibilities at JFK fluctuated between 1/8 and 3/16 of a mile.

1.8 Aids to Navigation

Not applicable.

1.9 Communications

No communications difficulties were reported.

1.10 Aerodrome and Ground Facilities

JFK is at an elevation of 12 feet. Runway 22R is 11,352 feet long and has RVR measuring equipment installed. Runway 22L is 8,400 feet long and is not equipped with RVR measuring equipment. Runway 13R is 14,5'2 feet long and is equipped with RVR measuring equipment.

1.11 Flight Recorders

1.11.1 Flight Data Recorder

The aircraft was equipped with a Fairchild Model 15600-501, Flight Data Recorder (FDR) serial No. 5148. There was no evidence of recorder malfunctions. The foil medium was undamaged and all parameter traces had been recorded clearly.

The recorded data were plotted for a 2-minute period beginning with the takeoff roll. Although the airspeed trace showed many aberrations during the takeoff, the data were failed and examined to determine airplane acceleration and distance. The examination showed that the airplane reached 164 km within 47 seconds, at which time a slight decrease

in altitude, indicative of liftoff; was recorded. The corresponding distance calculated from the rate of change in airspeed was approximately 7,500 feet.

One second later, 48 seconds after the start of the takeoff roll, excursions in vertical acceleration were recorded. Peak amplitude varied between +2 and 0 g for the next 5 seconds. Thereafter, all traces appeared normal for a departure climb.

1.11.2 Cockpit Voice Recorder

The cockpit voice recorder (CVR) is designed so that the recording tape operates in a continuous loop, erasing recordings every 30 minutes as new ones are added. Since the flight was airborne for several hours after the accident, any conversations recorded during the takeoff were erased.

1.12 Wreckage

Not applicable.

1.13 Medical and Pathological Information

There was no evidence of preexisting physical problems which could have affected the crewmembers' judgments or performances.

1.14 Fire

Vot applicable.

1.15 Survival Aspects

This was a survivable accident.

1.16 Tests and Research

None

1.17 Other Information

1.17.1 Airlift International Takeoff Data Computations and Procedures

Airlift International, Inc., employed the procedure of having the company agent prepare the weight and balance sheet, compute the takeoff "V" speeds, and compute other flight data for the crewmembers before the flight. The flight computations prepared for this flight were computed for a departure on runway 22R.

-7 -

The procedures also required the pilot to consult the Runway Analysis Manual if any of the precomputed takeoff conditions changed, including a change in the takeoff runway.

1.17.2 Performance Data

According to calculations furnished by the McDonnell-Douglas Corporation, the aircraft's performance from a standing takeoff, using normal takeoff procedures, was as follows:

The above $V_{LOF}$ represents the speed and distance obtained by the airplane at liftoff from the runway. The $V_{35}$ represents the speed and distance obtained at 35 feet above the runway's elevation with all engines operating.

2. ANALYSIS AND CONCLUSIONS

2.1 Analysis

The aircraft was certified, equipped, and maintained in accordance with FAA requirements and approved procedures.

Based on the investigation, the flightcrev's statements, and the performance analysis, the Safety board concludes that the aircraft's powerplants, airframe, electrical and pitot/static instruments, flight controls, and hydraulic and electrical systems were not factors in this accident. The flightcrew was route and airport qualified.

Because the captain was occupied with taxing in restricted visibility conditions, the responsibility for determining whether runway 22L was adequate for takeoff was assigned to the first officer. Instead of checking the appropriate data contained in the Runway Analysis Manual, the first officer looked at a taxiway and parking facilities chart which did not contain sufficient information from which to make this determination.

The Safety Board believes that the captain and the first officer were remiss in their duties since they did not determine that the aircraft could be operated safely from a different runway than that for which takeoff data had been calculated. The captain should have instructed one of the flightcrew to review specifically the Runway Analysis Manual to determine if the gross weight of the aircraft restricted a takeoff on runway 22L.

-8-

Since another DC-8 on the same ground control frequency requested a takeoff on a longer runway because his takeoff weight required the additional length, the flightcrew of Flight 101 should have been even more alert to the need to consult the manual. The manual would have indicated that the takeoff weight of the accident aircraft was 33,019 lbs. over the maximum weight allowed for takeoff or runway 22L.

A runway of adequate length with the required takeoff RVR was available to Flight 101 -- runway 13R. The runway was 14,572 feet long and had a reported RVR of 1,600 feet. Funway 13R would have been a logical choice for the weight of the aircraft.

Theoretical performance data showed that the airplane should have become airborne at an airspeed of 164 kn after a takeoff roll of 7,540 feet. The airspeed and altitude values recorded by the flight data recorder correspond to expected performance values and indicate that the airplane accelerated as expected. This evidence shows that the airplane became airborne within the confines of the runway; however, the distance from the threshold at which the takeoff thrust was established and the distance from the departure end at which the airplane actually lifted off could not be determined.

The Safety Board believes that the airplane lifted off near the end of the runway and that it was being rotated to the climb attitude when it struck the navigation aid structures beyond the runway's end.

Although the aircraft did become airborne, the insufficient runway length did not allow the margin of safety that is provided in the normal takeoff criteria as required by 14 CFR 121.189, which relates to takeoff requirements.

This accident demonstrates the need for flightcrews to be aware of the factors which can adversely affect the sale operation of their flight and to be familiar with, and use, all information that is available to them for this purpose.

2.2 Conclusions

(a) Findings

1. The crewmembers were certificated and qualified for the intended flight.

1. The aircraft was certified, equipped, and maintained in accordance with AA requirements and procedures.

-9-

1. The alircraft's weight, center of gravity, and loed distribution were within established limits.

1. The weight calculations were made for a takeoff on runway 22R; however, visibility on runway 22R precluded its use for takeoff.

1. The RVR on runway 22L was greater than required for takeoff and the captain elected to use the shorter runway.

1. The captain did not request that any of the crew-members consult the Runway Analysts Manual; the manual would have indicated that Flight 101 was 33,019 lbs overweight for a takeoff on the 8,400-foot runway.

1. A runway of sufficient length and with adequate visibility was also available for takeoff.

1. The takeoff was made on a runway that was too short for the performance capability of the aircraft. Consequently, the aircraft lifted off near the runway's end and there was not sufficient time or distance in which to rotate the aircraft and establish a climb.

1. The aircraft struck objects 1 foot above the elevation of the runway and 250 feet beyond the end of the runway. It also struck objects 4.5 feet above the runway elevation and 850 feet beyond the end of the runway.

1. The aircraft could not be pressurized properly because it was damaged during takeoff.

(b) Probable Cause

The National Transportation Safety Board determines that the probable cause of this accident was the captain's decision to use a runway that was too short for the aircraft's takeoff performance capability under existing loa and weather conditions. As a result, the aircraft struck obstacles beyond the departure end of the runway before it began to ciimb. The flightcrew had failed to use available data which would have informed them that the runway was not long enough for the takeoff.
