## Analysis

After landing, the pilot of the Cessna 172R was instructed by air traffic control to expedite his crossing of a parallel runway, and to pull-up along the left side of a stopped Boeing 767-300. The Boeing subsequently continued its taxi, and made a right turn. During the turn, the Cessna was flipped onto its left wing, due to the Boeing's jet blast. The Cessna sustained substantial damage to the left wing spar.

## Factual narrative

On September 4, 2007, about 1405 eastern daylight time, a Cessna 172R, N445AF, was substantially damaged while taxiing at the General Edward Lawrence Logan International Airport (BOS), Boston, Massachusetts. The certificated private pilot and a pilot rated passenger were not injured. Visual meteorological conditions prevailed and an instrument flight rules flight plan had been filed for the flight that departed Laurence G Hanscom Field (BED), Bedford, Massachusetts. The personal flight was conducted under 14 Code of Federal Regulations Part 91.

According to the pilot and a Federal Aviation Administration (FAA) inspector, the airplane landed uneventfully on runway 33R, made a left turn onto taxiway "N," and was holding short of runway 33L. Air traffic control then instructed the pilot to expedite crossing runway 33L, and to pull-up along the left side of a stopped Boeing 767-300. The Boeing subsequently continued its taxi, and made a right turn onto taxiway "K". During the turn, the Cessna was flipped onto its left wing, due to the Boeing's jet blast.

The Cessna sustained substantial damage to the left wing spar.

The pilot further reported that the airplane's ailerons were properly positioned for the crosswind generated by the jet blast when the airplane was upset.
