Airworthiness Directives; Beech Aircraft Corporation 35 Series Airplanes Federal Register ↗

Abstract

This amendment supersedes Airworthiness Directive (AD) 57-18- 01 and AD 87-20-02 R1, which currently require several ruddervator checks and modifications on certain Beech Aircraft Corporation (Beech) 35 series airplanes. This action maintains the requirements of each of the superseded AD's and requires rebalancing the ruddervators (off the airplane) anytime the ruddervator is repaired or repainted (even if stripes are added). The required action imposes no new speed restrictions. Several incidents where empennage flutter occurred on the affected airplanes prompted this action. The actions specified by this AD are intended to prevent structural failure of the V-tail, which could result in loss of control of the airplane.
