Probable cause

Structural damage sustained by the Bellanca, N39843, as a result of encountering wake turbulence during a near-collision with a navy F-14A.

Analysis

The navy pilot had received clearance to descend from 9,000 ft to 5,000 ft on a south-easterly course. The westbound Bellanca was cruising in level flight at 8,500 ft. VFR conditions prevailed. When the two airplanes were between 100-300 ft of each other, the navy pilot observed the target and abruptly pulled up. The Bellanca passed beneath the F-14 and encountered its wake. Both airplanes landed without further incident. The Bellanca's right wing's rear main wooden spar was found broken. At the time, the F-14 was being radar controlled by a trainee controller under direct supervision. The supervisor had observed the possible traffic conflict, and had directed the trainee to inform the F-14. Responding to the advisory, the pilot of the F-14 observed the traffic and took evasive action.
