Circumstances:
During arrival, the aircrew of a Gates Learjet 35A, N873LP, canceled their IFR clearance and contacted the Auburn unicom, then entered the traffic pattern to land on runway 18. The unicom operator reported that the Learjet crew had reported their position on each portion of the traffic pattern. At approximately the same time, the pilot of an unregistered, experimental, Challenger II was in the traffic pattern for runway 10. The two runways intersected at their approach ends. Just before landing, the two aircraft collided as they were crossing over the intersection and crashed on the airport. The challenger (a two place version of an ultralight vehicle) was not equipped with a radio and the unicom operator was unaware of its presence in the traffic pattern. The Learjet pilot stated that neither he nor his copilot had seen any other traffic at the airport. No indication was found that either crew had taken evasive action. An exam of the crash site revealed evidence that the collision had occurred approximately 50 feet above the intersection. A pilot on board the Learjet was killed while six other occupants were injured. The pilot of the Challenger II was also killed.

Circumstances:
During an IFR arrival/descent, the pilot stated he 'had to feather one engine, I have an oil leak and I'm just trying to descend . . .' he then said he was descending thru 5,300 feet. As he continued the approach, he informed the controller he would be unable to go around since the hydraulic system was powered by the affected right engine. Subsequently, the pilot said he was at 1,500 feet and was having a hard time holding altitude. A witness heard and saw the aircraft in a level attitude at low altitude, then saw the aircraft dive toward the ground. It impacted in a steep descent just short of a long field and burned. The right propeller was feathered, but there was no evidence of oil starvation in either engine. The pilot's neighbor said he (the pilot) was aware of a hydraulic leak, but he was awaiting the annual inspection (due in September) to repair it. An exam revealed the flaps were partially extended, the landing gear control was in the 'up' position, and the gear was down. The flight manual stated that with a hydraulic failure downstream of the accumulator, the flap handle should be in 'neutral' to prevent gear and flap extension. The flap control could not be found. All six occupants were killed.

Circumstances:
At 2045 the military flight, Dixie 06, contacted Birmingham approach and obtained clearance for a low approach followed by a full-stop landing on runway 05. At 2053, Dixie 06 reported a 4 mile final for a low approach to the local controller. At 2054:19, the local controller cleared ABX74, N19T, '...taxi position and hold five.' ABX74 was awaiting takeoff instructions on runway 05 when the collision occurred. Investigation revealed the local controller forgot ABX74. She became preoccupied with other traffic using runway 36. The local controller termed the traffic as busier than normal for a night operation. At the time of the accident, the tower was staffed with two air traffic controllers and an air traffic assistant. No supervisor or coordinator was available in the cab to detect controller overload and offer assistance. The pilot, sole on board, was killed. The military aircraft involved in the collision was a USAF Douglas RF-4C Phantom II registered 64-1032 with two pilots on board. They escaped uninjured.

Circumstances:
Shortly after climbing and leveling at 6,000 feet, the right engine bmep gage indicated a rapid power loss and the right engine rpm 'increased out of control' to about 3,100 rpm. The aircrew retarded the right throttle and reduced the right engine to 2,100 rpm by using the prop increase/decrease toggle switch. The aircrew were unable to feather the right propeller or maintain altitude, so they diverted to the nearest airport (Walker County). While turning downwind for runway 09, the right engine fire indicator activated and the copilot confirmed a fire. Both fire bottles were discharged and the right propeller stopped rotating. Injection water for the left engine was exhausted and the left engine began backfiring. The captain then maneuvered and landed on runway 27. After touchdown, the right main tires failed, the aircraft veered off the right side of the runway and hit a ditch and the gear collapsed. An exam revealed the #6 cylinder link rod and/or piston in the right engine had failed, resulting in further damage to the engine and #6 cylinder. Subsequently, fire and heat caused the right engine to seize and also damaged the right main tires which failed at touchdown. All 39 occupants were evacuated, among them two passengers were seriously injured.

Witnesses described 200 feet ceiling and reduced visibility in fog at airport. Other witnesses observed aircraft on northbound course, followed by turn to west at rooftop height, well below MDA, at a point one mile northeast of airport. Engine operation sounded normal. Aircraft contacted trees at about airport elevation, one mile north of airport. Wreckage produced 632 feet path. Severed limbs, prop damage and engine examination revealed evidence of power at impact. 62 year old pilot had not flown with cfi in years, instrument currency unknown.

Circumstances:
The pilot stated that during takeoff roll he experienced a power surge but the engine did not quit. He aborted the takeoff by reducing power on both engines and applying brakes. This resulted in the aircraft swerving off the right side of the runway, rolling thru the grass and striking a culvert which separated the landing gear. Wreckage examination revealed: both throttles at idle, mixture and prop controls were full forward and full rich and high rpm on respective engine controls. All cables attaching hardware was intact.

Circumstances:
About 20 minutes after takeoff the pilot reported the right engine had lost power and the aircraft would not maintain altitude. Vectors were provided for an emergency landing, but the aircraft crashed in a wooded area about 3 miles from the airport. There was evidence that the gear and flaps had been extended and the aircraft had entered a turn before impacting. Both props had evidence of low to moderate power and neither was feathered. An exam revealed unsymmetrical wear on the blades of the right turbocharger; its thrust spacer, pn 406990-9004, was worn and there was evidence of oil leakage. The 13 qt, right engine oil system had only 6.85 qts of oil remaining. Both turbochargers had been installed during an annual inspection in april 1983 and previously had been overhauled. The aircraft was estimated to be 844 lbs over its max weight limit and the aircraft cg limit was exceeded by about 4.8 inches. Six of the passengers were not restrained by seat belts. An associate estimated that the pilot had only 4 to 6 hours of rest in the previous 3 to 4 days. All eight occupants were killed.
