(e) Reason This AD was prompted by a loss of engine power in flight caused by oil leaking from the gearbox radial shaft sealing ring that contaminated the clutch. We are issuing this AD to prevent failure of the clutch, loss of engine power in flight, and reduced control of the airplane. (f) Compliance (1) Comply with this AD within the compliance times specified, unless already done. (2) Within 55 flight hours after the effective date of this AD: (i) Replace the clutch with a dual mass flywheel.

(ii) Install a start phase monitoring system and software mapping in accordance with the requirements of FAA AD 2015-21-01 (80 FR 64314, October 23, 2015); and (iii) Inspect the rear radial shaft sealing ring on the gearbox for oil leakage in accordance with Figures 2 and 3 of Technify Motors SB No. SB TMG 125-1020 P1, Initial Issue, dated January 27, 2016. If an oil leak is detected, replace the gearbox with a part eligible for installation before the next flight. [[Page 44713]] (g) Installation Prohibition After the effective date of this AD: (1) Do not install an engine that is equipped with a clutch and has an affected gearbox listed in Figure 1 to paragraph (c) of this AD; (2) Do not install an affected gearbox on an engine unless it has passed the inspection required by paragraph (f)(2)(iii) of this AD; and (3) Do not install a clutch on an engine previously modified in accordance with the requirements of paragraph (f)(2) of this AD or already incorporating a dual mass flywheel.
