Airworthiness Directives; Commander Aircraft Company Model 114TC Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to certain Commander Aircraft Company (Commander) Model 114TC airplanes. This AD requires you to replace the existing Aeroquip V-band exhaust clamp with a new clamp of improved design. This AD is the result of reports of this clamp failing on 4 of the affected airplanes. This clamp attaches the exhaust stack to the turbocharger. The actions specified in this AD are intended to prevent the exhaust stack from detaching from the turbocharger due to failure of the V-band exhaust clamp. This could result in the release of high temperature gases inside the engine compartment with a consequent airplane cabin fire.
