The FAA adopts a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Models 172R, 172S, 182T, T182T, 206H, and T206H airplanes. This AD requires you to inspect any MC01-3A I.C. 9 or MC01-3A I.C. 10 main electrical power junction box circuit breakers for correct amperage (amp) (a correct 40-amp circuit breaker) and replace any incorrect amp circuit breaker with the correct 40-amp circuit breaker. This AD results from several reports of circuit breakers that are not the correct 40-amp circuit breaker installed in the MC01-3A main electrical power junction box. We are issuing this AD to replace any incorrect circuit breaker installed in the MC01-3A I.C. 9 or MC01-3A I.C. 10 main electrical power junction box, which could result in premature tripping of the power junction box main feeder circuit breakers and could lead to partial or complete loss of all electrical power on the airplane. This condition could lead to the loss of all navigation and communication equipment and lighting in the cockpit.
To address this problem, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Inspect any MC01-3A I.C. 9 (part number (P/N) S3100-297) or MC01-3A I.C. 10 (P/N S3100-344) main electrical power junction box for any incorrect amperage (amp) circuit beaker installed in place of the required 40-amp circuit breakers | Within the next 30 days after August 9, 2005 (the effective dated date of this AD), unless already done | Follow Cessna Service Bulletin No. SB05-24-01, January 31, 2005. |
| (2) Replace any incorrect amp circuit breaker with the required 40-amp circuit breaker | Before further flight after the inspection required by paragraph (e)(1) of this AD | Follow Cessna Service Bulletin No. SB05-24-01, dated January 31, 2005. |
| (3) Only install in any MC01-3A I.C. 9 (P/N S3100-297) or MC01-3A I.C. 10 (P/N S3100-344) main electrical power junction box the required 40-amp circuit breakers | As of August 9, 2005 (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.
