Accident Details
The pilot reported that the aircraft had been taxiing at idle speed for approximately one and a half hours before receiving takeoff clearance. During the takeoff roll, the pilot noted that the acceleration felt "sluggish." As the aircraft climbed, the engine misfired. The airplane reached an altitude of about 200 feet before the engine lost power entirely. The pilot then executed a landing on runway 21, during which the aircraft rolled off the overrun.
Aircraft Examination
Post-accident examination revealed structural damage to the left and right wing assemblies, including spar damage. The fuselage was buckled, and the main landing gear was sheared off. All flight control surfaces were inspected and found to be operating correctly.
Engine Run-Up
A run-up of the engine was conducted following the accident. During this test, the engine attained a maximum of 800 rpm.
Pilot Operating Handbook and Weather Conditions
A review of the Piper Cherokee Pilot's Operating Handbook, specifically the section on Warm-up and Ground Check, notes that carburetor heat should be checked prior to takeoff to ensure proper control operation and to clear any ice that may have formed during taxiing. Weather data from the time of the accident indicated conditions favorable for the formation of carburetor ice. The pilot did not report checking the carburetor heat following the prolonged ground operation.
