Airworthiness Directives; Beech Aircraft Corporation 35 Series Airplanes
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 This action maintains the requirements of each of the superseded AD's and requires rebalancing the ruddervators (off the airplane) anytime the ruddervator is repaired or repainted (even if stripes are added).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.
Applicability
Aircraft makes and models this AD applies to, sorted by US-registered fleet size.
Compliance instructions
The full AD text — required actions, compliance times, parts/serial numbers, and methods of compliance — is in the Federal Register publication. We do not paraphrase ADs because misreading the compliance instructions is a safety risk.
