Flight History
A pilot departed on a cross-country flight under visual flight rules and obtained flight following from air traffic control facilities along the intended route. While en route, after encountering instrument meteorological conditions at 2,500 feet, the pilot received an instrument flight rules (IFR) clearance. The flight was then provided radar vectors to intercept the instrument landing system (ILS) runway 4 approach for the destination.
Radar track data indicated that the aircraft passed through the localizer centerline at 2,400 feet and then made a rapid right turn back toward the centerline. Subsequently, the airplane performed a series of rapid descents and climbs, along with several course reversals, over a 75-second period. During this time, the pilot reported an unspecified problem, and his last communication was "I can go out now ... flying eastbound."
A witness reported seeing the aircraft flying about 20 feet above the ground before it entered a steep climb. The witness then heard an increase in engine noise, followed by a loud boom. The airplane impacted approximately 3.5 miles outside the locator outer marker along the localizer centerline.
Weather Conditions
Instrument meteorological conditions prevailed at the destination airport at the time of the accident. The reported ground visibility was 2.5 miles in mist, and the ceiling was overcast at 500 feet.
Pilot Background
Based on available information, the pilot had not recorded an instrument approach in over six months prior to the accident. Additionally, his last flight review was completed more than 24 months before the accident. No additional dual flight instruction or instrument proficiency checks were uncovered during the investigation.
Wreckage Examination
A review of the maintenance records found no history of unresolved airworthiness issues. Examination of the recovered wreckage revealed no evidence of a pre-impact mechanical malfunction.
