Airworthiness Directive · Amendment 39-11752 · Commander Aircraft Company Model 114TC Airplanes
Commander Aircraft Company Model 114TC Airplanes
Model 114TC airplanes, serial numbers 20001 through 20027, certificated in any category.
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.
To address this problem, you must accomplish the following:
| Action | Compliance time | Procedures |
|---|---|---|
| (1) Replace the Aeroquip V-band exhaust clamp (Aeroquip part number 00624-55677-340M or Lycoming alternate part number 40D21162-340M) with a part of improved design (Aeroquip part number NH1009399-10) | Accomplish this action within the next 25 hours time-in-service after June 23, 2000 (the effective date of this AD | Perform this action in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of commander Aircraft Company Service Bulletin No. SB-114-33A, dated May 9, 2000. |
| (2) Do NOT install an Aeroquip V-band exhaust clamp (Aeroquip part number 00624-55677-340M or Lycoming alternate part number 40D21162-340M) on any affected airplane | As of June 23, 2000 (the effective date of this AD) | Not applicable. |
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
