Airworthiness Directive · Amendment 39-16296 · Mitsubishi Heavy Industries, Ltd. Various Models MU-2B Airplanes
Mitsubishi Heavy Industries, Ltd. Various Models MU-2B Airplanes
This AD applies to the following airplane models and serial numbers that are certificated in any category:
| Models | Serial Nos. |
|---|---|
| MU-2B-25, MU-2B-26, MU-2B-26A, MU-2B-36A, MU-2B-40, and MU-2B-60 | All serial numbers. |
| MU-2B-35 and MU-2B-36 | There are no serial numbers for MU-2B-35 or MU-2B-36 under TCDS A10SW. |
| Models | Serial Nos. |
|---|---|
| MU-2B, MU-2B-10, MU-2B-15, MU-2B-20, MU-2B-25, MU-2B-26, MU-2B-30, MU-2B-35, MU-2B-36 | All serial numbers. |
We are adopting a new airworthiness directive (AD) to supersede Airworthiness Directive (AD) 2006-17-01, AD 2006-15-07, AD 2000-02-25, and AD 97-25-02, which applies to certain Mitsubishi Heavy Industries, Ltd. (MHI) various Models MU-2B airplanes. An FAA MU-2B safety evaluation resulted in the standardization of the MU-2B specific training and the FAA-accepted pilot operating checklists through a special Federal aviation regulation (SFAR). MHI revised the airplane flight manuals (AFMs) to align them with the information in that training and the checklists. In addition, incorporating all AFM revisions up to and including this latest AFM revision will incorporate all AFM compliance actions required by the four above-mentioned ADs. This AD would retain from AD 2006-17-01 the inspection of the engine torque indication system and possible recalibration of the torque pressure transducers and would require incorporating all revisions up to and including the latest revisions of the AFM. We are issuing this AD to correct inconsistencies in critical operating procedures between the MU-2B specific training, the FAA-accepted pilot operating checklists, and the AFMs, which, if not corrected, could result in the pilot inadvertently taking inappropriate actions in critical operating conditions.
Do the following unless already done:
(1) Within 100 hours time-in-service (TIS) after September 22, 2006 (the effective date retained from AD 2006-17-01), inspect the engine torque indication system and, before further flight after the inspection, recalibrate the torque pressure transducers as required. For airplanes listed in TCDS A2PC, follow MHI MU-2 Service Bulletin No. 233A, dated January 14, 1999 or MHI MU-2 Service Bulletin No. 233B, dated March 8, 2007. For airplanes listed in TCDS A10SW, follow MHI MU-2 Service Bulletin No. 095/77-002, dated July 15, 1998. This inspection requires the use of the following power assurance charts as applicable:
(i) If you have not incorporated the AFM revisions required in paragraph (e)(2) of this AD: Use the power assurance charts referenced in Table 3 below; or
(ii) If you have already incorporated the AFM revisions required in paragraph (e)(2) of this AD: Use the power assurance charts in section 6 of the revised AFMs required by paragraph (e)(2) of this AD.
