This AD applies to The Boeing Company Model 757-200 series airplanes, certificated in any category, modified by the applicable supplemental type certificate identified in paragraphs (c)(1) and (c)(2) of this AD.
(1) ST01529SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/0af09c3701a237ee86257a5d0064b3aa/$FILE/ST01529SE.pdf).
(2) ST02278SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/e54b5289a2e9f6ef86257b7f0056edaf/$FILE/ST02278SE.pdf).
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757-200 series airplanes modified by particular STCs. This AD was prompted by reports of a main cargo door being blown past its full open position while on the ground during gusty wind conditions, which resulted in uncontrolled fall down to its closed position. This AD requires installing a new placard and bracket, replacing an existing placard, and replacing the main cargo door control panel. We are issuing this AD to prevent damage to the main cargo door, which could result in rapid decompression of the airplane, or injury to maintenance and ground crew during ground operations.
Within 90 days after the effective date of this AD, install a new placard and bracket, replace the existing placard, and replace the main cargo door control panel, in accordance with the Accomplishment Instructions of Precision Conversions Service Bulletin PC-757-11-0023, dated August 1, 2014.
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.
