HISTORY OF FLIGHT

On July 22, 2003, at 0859 eastern daylight time, an unregistered Hawker Hunter T Mk. 7A, was destroyed when it struck terrain in Pittston, Pennsylvania, after it departed from Wilkes-Barre/Scranton International Airport (AVP), Avoca, Pennsylvania. The airplane was owned and operated by Northern Lights Aerobatic Team, Montreal, Quebec, Canada. The certificated commercial pilot was fatally injured. Visual meteorological conditions prevailed for the positioning flight. No flight plan had been filed for the flight that was destined for Burlington International Airport (BTV), Burlington, Vermont, and was conducted under 14 CFR Part 91.

The owner reported that the purpose of the flight was to position the airplane from Wilkes-Barre, to Burlington, where he planned to apply for an import certificate to bring the airplane into Canada. The owner further reported that he had not applied to Transport Canada, for a Canadian registration and airworthiness certificate.

The pilot had performed three aborted takeoffs in the 4 days that preceded the accident flight. The people on scene during the aborted takeoffs and accident flight were the owner, and two non-certificated mechanics.

The air/ground communication tapes received from the Federal Aviation Administration (FAA), control tower were reviewed, and transcripts prepared for each aborted takeoff. Each aborted takeoff was preceded by the departure of a Piper Navajo, PA-31-350, Canadian registration C-GULM, which was registered to the operator. The Navajo was piloted by the owner, and in addition carried the two non-certificated mechanics. Each flight was announced as a flight of two, proceeding to Burlington in visual meteorological conditions.

The first aborted takeoff occurred on July 18, with the airplane using runway 04. The pilot reported the engine was a little cool, but there were no problem with it. He did report that the brakes appeared to be dragging. Air was subsequently found in the brake lines, and they were bleed.

The second aborted takeoff occurred on July 19, 2004, with the airplane using runway 04. The pilot used the drag chute; however, the airplane overran the departure end of the runway. Again the pilot reported no problems with the engine, and that the brakes were dragging. A check of the airplane revealed the brake cables in the cockpit were out of adjustment, and they were adjusted.

The assistant airport director reported that after the second aborted takeoff, he was called to the airport due to an observed fuel leak on the Hawker Hunter. He stated:

"...[the pilot] stated that the anti-skid system, called the 'Maxarrets' system, had started to cycle or pulse at high speed giving him the feeling that the brakes were cycling 'on-off' at this higher speed without input from the pilot. At that time, I directly expressed my concern that this abort was a close call and I asked the pilot if he realized that we had very little RSA [runway safety area] and that even if he went over the end at 1 mph he was in trouble as it was a substantial drop off. His response was that he would worry about flying the aircraft, or 'I'll fly the aircraft...' and I[assistant airport director] should worry about, or be concerned about airport matters. The pilot said that the brake system was the problem and that his mechanics were coming back to address the problem that evening. He did express his frustration with the fact that he had apparently had several aborts or attempts to depart and that he had commercial tickets to get back home as he has other commitments and that this ferry flight was dragging out. He said he had rescheduled his commercial tickets at least twice and had current departure reservations in hand. He said he would have departed commercially except that the aircraft owner had asked that he stick with it and give it another try. He definitely was ready to leave one way or the other...."

The third aborted takeoff occurred on July 21, 2003, with the airplane using runway 22. The pilot reported the engine was OK, and the brakes were dragging. The airplane was examined, and nothing was found. No further maintenance was performed on the airplane. The pilot then performed a high speed taxi, and said that he would take the airplane the next morning.

On the day of the accident, a FAA operations inspector reported that he had a general conversation with the pilot earlier in the morning. At one point, the FAA inspector asked the pilot if he knew how long it had been since the airplane had flown. The pilot reported that he thought it was 2 or 3 months. The FAA inspector reported that he turned to a mechanic who was familiar with the airplane and the mechanic reported that it had been over a year. At that point, the pilot exhibited a facial expression that the FAA inspector interpreted as surprise. The conversation terminated shortly thereafter, and the two parted company. The FAA inspector reported that he was left with a feeling that the pilot was confident that the airplane was airworthy, and that he could handle any emergency, which might arise in the flight. The pilot added that he had made several high-speed aborts, the reason for which were not specified.

The airplane taxied to runway 22 for departure as the second airplane in a flight of two. The radio communications for both airplanes was being handled by the pilot of the Navajo, which was the lead airplane for the flight.

At 0856:46, the pilot of the Navajo reported that he was ready for departure, and that the Hawker Hunter would back taxi for departure. The flight was cleared for takeoff at 0856:48.

At 0859:54, the pilot of the Navajo transmitted:

"...scranton tower declaring an emergency, we have a hunter, it is down."

The pilot of the Navajo returned for landing. However, he was held until the runway was checked, after which he was cleared to land.

The takeoff on runway 22 was observed by several witnesses. They were consistent in reporting that the engine did not sound as loud as they expected; the airplane did not seem to be accelerating like they expected, and the airplane did not rotate until it was near the end of the runway. One witness, also a pilot, reported the nose of the Hawker Hunter came up abruptly to between 20 and 30 degrees, and the airplane became airborne. However, once airborne, the wings started to rock from side to side, and then the airplane disappeared from view as it descended below the level of the terrain, beyond the departure end of the runway.

Additional witnesses saw the airplane in a nose high pitch attitude as it descended toward terrain near the accident site. One witness described the pitch attitude of the airplane as near a normal take off when first observed. As he continued to watch, the pitch of the airplane continued to increase to about 30 degrees nose up as the airplane continued to descend. The witness said he could hear the engine running. The airplane descended below his view, and then he heard a loud bang, and saw smoke and flames rising from a wooded area.

A non-certificated mechanic onboard the Navajo reported that he observed the takeoff roll, and when the airplane was about halfway down the runway, it appeared to slow, as if the pilot was aborting the takeoff, and then as it moved further down the runway, the airplane appeared to be accelerating again. The airplane appeared slow as it approached the end of the runway, and then he saw the nose come up. As the airplane passed the departure end of the runway, he saw the pilot make a shallow left turn to avoid the opposite direction approach lights that were located beyond the departure end of the runway. He saw the airplane intact as it went into the woods except for the drop tanks, and then he saw a big ball of fire. He never observed the ejection seat come out the airplane.

An FAA airworthiness inspector reported that after the Navajo landed, he approached the occupants and asked who they were. After identifying themselves, he then asked if they owned the Hawker Hunter that just crashed, and the owner said yes he did. He then asked that individual if he knew where the maintenance records were for the airplane, and the owner reported that they were on the crashed airplane. The FAA inspector further reported that he asked the owner if he could remain in the area until the FAA had a chance to interview him, and he replied that he would.

The FAA inspectors then traveled to the accident site and were there about 1 to 2 hours. Upon returning to the airport, the Navajo, along with the owner and the two other people had departed.

The accident occurred during the hours of daylight at 41 degrees 18.949 minutes north latitude, and 75 degrees, 44.415 minutes west longitude.

PERSONNEL INFORMATION

The pilot held a commercial pilot certificate with single engine and instrument airplane ratings. He was last issued a second class FAA airman medical certificate on September 4, 2002. He held a current Letter of Authority for the Hawker Hunter, which expired December 11, 2003. In his last request for renewal, the pilot reported that he was a Hawker Hunter demo instructor pilot for Aero Group, and F-104 demo/instructor pilot for Starfighters, Inc. The Letter of Authority required that the pilot have three takeoffs in the Hawker Hunter or comparable aircraft within the preceding 6 calendar months. In addition, it stated that after a 6 calendar month period of inactivity, the pilot was to obtain a flight review, including normal and emergency procedures and maneuvers in the Hawker Hunter and have his pilot logbook endorsed. At the time of the accident, the pilot was also flying a Lockheed F-104 in the air show circuit.

According to records from the pilot's electronic pilot logbook, which was current through March 10, 2003, the pilot's total flight experience was 6,574.2 hours, which included 235.2 hours in the Hawker Hunte...
