Airworthiness Directive · Amendment 39-11818 · Short Brothers Model SD3-60 Series Airplanes
Short Brothers Model SD3-60 Series Airplanes
Model SD3-60 series airplanes, certificated in any category, serial numbers SH3716 through SH3763 inclusive.
Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD), applicable to certain Short Brothers Model SD3-60 series airplanes, that requires affixing a label containing revised engine limitations on the ditching hatch, and revising the airplane flight manual to reflect the revised engine limitations. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent the use of incorrect engine limitations, which could result in an overspeed of the propellers and potential for blade failure.
To prevent the display of incorrect engine limitations, which could result in an overspeed of the propellers and potential for blade failure, accomplish the following:
(a) Within 6 months after the effective date of this AD: Replace the existing engine-limitations label with a new label containing revised engine limitations, and revise the Limitations section of the FAA-approved airplane flight manual to reflect the revised engine limitations; in accordance with Shorts Service Bulletin SD360-11-23, dated November 17, 1998.
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.
