Alan Kulwicki plane crash

At 14:21 local time the pilot filed a series of instrument flight plans with the Georgia Automated Flight Service Station at Macon, Georgia.

At 20:58 the flight departed McGhee Tyson Airport near Knoxville, Tennessee, on a business flight bound for Tri-Cities Regional Airport at Blountville, Tennessee, with a valid instrument flight clearance.[1]

At 21:10 while cruising at 7,000 feet the flight was contacted by Tri-City Airport TRACON and notified to anticipate an instrument landing system (ILS) approach to Runway 23.

At 21:28 the pilot reported "We are outside the marker" and was cleared to land by air traffic control.[2]

At 21:29 radio contact between the air traffic controller and the pilot was lost. Following an uncontrolled descent the aircraft impacted the downhill side of a meadow 5.5 miles northeast of the airport, approximately 0.5 miles from the outer marker beacon.[1] The main wreckage of the aircraft came to rest approximately 60 feet from the initial impact point on a heading of 240 degrees. All four people on board were killed in the crash. A post crash fire consumed the cockpit, center section and the left wing.[1]

The aircraft involved was a Fairchild SA227-TT Merlin pressurized, twin turboprop business aircraft, serial number TT-527, and was equipped with Garrett TPE331 engines. The aircraft was issued an FAA airworthiness certificate on 6 September 1985 and registered number N500AK.[3]

At the time of the accident, the airframe had accumulated 2,294 hours and had its last inspection 50 hours prior. The Fairchild was listed as doing business for Eastern Foods Inc. as a Hooters corporate aircraft and the registered owner/operator was Robert H. Brooks.[1]

The pilot and sole crew member was 48-year-old Charlie Campbell, hired by Eastern Foods Inc. on January 27, 1992 as their primary pilot. Campbell held a valid FAA Certificate as an Airline Transport/Commercial pilot and had a total flight time of 19,105 hours including 235 hours in the Fairchild Merlin. Campbell was type rated in the accident aircraft as well as the Beechjet 400 and McDonnell Douglas DC-9.[1]

The National Transportation Safety Board (NTSB) investigated the accident and released its report on March 16, 1994. During a post accident interview the air traffic controller stated he had watched the aircraft on final approach until it disappeared from view, then heard a pilot make a radio transmission that he could not understand, then witnessed the aircraft lights in a steep spiral falling from the bottom of the cloud level.[1] The aircraft experienced icing conditions before approaching the airport and radar information showed the aircraft slowed substantially and began a rapid descent before the crash.[1]

From examination of the physical evidence it was discovered that neither engine was functioning and that both propellers were feathered at the time of impact. No evidence of any aircraft system failure before the crash was found. The NTSB report stated in part that "There was evidence that engine inlet anti-ice annunciator lights were illuminated during impact" which led to the determination that the probable cause of the accident was "Failure of the pilot to follow procedures concerning the use of the engine inlet anti-ice system and/or continuous ignition while operating in icing conditions."[1]
