Airworthiness Directive 95-23355
one-timeAirworthiness Directives; Twin Commander Aircraft Corporation 680, 681, 690, and 695 Series Airplanes
What this AD requires
This amendment adopts a new airworthiness directive (AD) that applies to certain Twin Commander Aircraft Corporation (Twin Commander) 680, 681, 690, and 695 series airplanes. This action requires installing a placard warning the pilot to observe turbulent air penetration speeds. Two accidents involving Model 690 airplanes where the affected airplanes encountered turbulence while descending at high speeds prompted this action. The actions specified by this AD are intended to prevent structural damage to the airplane caused by excessive turbulence, which could result in loss of control of the airplane.
Which aircraft AD 95-23355 applies to
certain
Whether AD 95-23355 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
