Airworthiness Directive · Amendment 39-14658 · Pacific Aerospace Corporation Ltd. 750XL Airplanes
Pacific Aerospace Corporation Ltd. 750XL Airplanes
Superseded. A later AD replaced this one: AD 2016-14-06. Comply with the one in force.
This AD affects Model 750XL airplanes, serial numbers 101, 102, 104 through 120, and 125, that are certificated in any category.
We are adopting a new airworthiness directive (AD) that supersedes AD 2005-26-53, which applies to certain Pacific Aerospace Corporation Ltd. (PAC) 750XL airplanes. AD 2005-26-53 currently requires you to insert text into the Limitations Section of the Airplane Flight Manual (AFM) that reduces the maximum takeoff weight from 7,500 pounds to 7,125 pounds. This AD results from mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for New Zealand and the FAA's decision that the actions correct an unsafe condition. Consequently, this AD would require you to remove rivets that have not been fully age hardened and replace them with bolts, washers, and nuts in specific locations where reduction in rivet strength affects overall structural capability. This AD retains the actions of the previous AD until the rivets are replaced with the bolts, washers, and nuts. We are issuing this AD so that wing ultimate load requirements are met. If wing ultimate load requirements are not met, wing failure could result with consequent loss of control of the airplane.
To address this problem, you must do the following:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Insert the following information into the Limitations Section of the Airplane Flight Manual (AFM). You may do this by inserting a copy of this AD into the Limitations Section of the AFM “The maximum takeoff weight is reduced from 7,500 pounds to 7,125 pounds” | Before further flight after January 16, 2006 (the effective date of AD 2005-26-53), except for those who received emergency AD 2005-26-53, issued December 22, 2005, unless already done. Emergency AD 2005-26-53 continued the requirements of AD 2005-26-53 and became effective immediately upon receipt | The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may do the flight manual changes requirement of this AD. Make an entry in the aircraft records showing compliance with this portion of the AD following section 43.9 of the Federal Aviation Regulations (14 CFR 43.9). |
| (2) Remove rivets, part number (P/N) MS20470 DD6, and replace with bolts, P/N NAS 6203-7X or NAS 6203-6X; washers, P/N AN960-10; and nuts, P/N MS21044N3 | Within 100 hours time-in-service after the effective date of this AD | Following Pacific Aerospace Corporation Ltd. Service Bulletin PACSB/XL/018 Issue 3, issued December 23, 2005, and amended January 16, 2006. |
| (3) Remove the restrictive information from the Limitations Section of the AFM that you were required to insert in paragraph (e)(1) of this AD | After doing the action required in paragraph (e)(2) of this AD | The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may do the flight manual changes requirement of this AD. |
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.
