On May 31, 2015, about 2000 Alaska daylight time, a tailwheel-equipped Piper PA-22 airplane, N2828P, sustained substantial damage after impacting terrain while maneuvering at low level about 17 miles southeast of Skwentna, Alaska. The student pilot and sole occupant received minor injuries. The airplane was registered to, and operated by, the pilot under the provisions of Title 14 Code of Federal Regulations (CFR) Part 91 as a personal cross-country flight. Visual meteorological conditions prevailed at the time of the accident, and no flight plan had been filed. During an interview with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on June 01, 2015, the pilot stated that he was maneuvering the airplane to "drag the runway" of an unimproved airstrip. After passing over some trees in a northerly direction, the airplane began a rapid descent. The pilot applied full power in an effort to correct for the descent, but the engine power decreased. About 25 feet above ground level (agl), the left wing struck a tree, and the airplane impacted terrain in a slight left bank. The airplane slid along the surface for about 18 feet before impacting a berm, which caused the airplane to become airborne and rotate counter clockwise 180 degrees before coming to rest in a near level pitch attitude. During a post-accident examination of the airplane, including maintenance records, it was discovered that Federal Aviation Administration (FAA) Airworthiness Directive (AD) 73-09-06 was applicable to Piper PA-22-150 airplanes with Lycoming O-320 series engines and Marvel Schebler Carburetors Model MA-4-SPA, part numbers 10-3678-11, 10-3678-12, and 10-3678-32. The accident airplane was equipped with a Lycoming O-320 engine and a Marvel Schebler Carburetor, model number MA-4SPA, P/N 10-3678-32, and the airplane was in compliance with the AD by having the required placard in place at the time of the accident. The AD states, in part: "To prevent power interruption and acceleration hangup resulting from abrupt throttle movement, accomplish the following: Attach the following operating limitation placard to the instrument panel near the throttle in full view of the pilot. Use 1/8 inch min. size lettering. 'DO NOT OPEN THROTTLE RAPIDLY – (IDLE TO FULL THROTTLE, 2 SECONDS MINIMUM)' The placard may be fabricated by the owner or operator." The pilot stated that when he advanced the throttle, he did so in a rapid motion, faster than the 2-second requirement. The closest weather reporting facility is Skwentna Airport, about 17 miles northwest of the accident site. At 1850, an aviation routine weather report (METAR) from the Skwentna Airport was reporting in part: winds from 290 degrees at 7 knots; visibility, 30 statute miles; sky condition, few clouds at 3500 feet, scattered at 20000 feet; temperature 77 degrees F; dewpoint 37 degrees F; barometric pressure 29.74inHG.
