REGULATORY TEXT:  
90-14-01 FAIRCHILD AIRCRAFT CORPORATION (formerly Swearingen Aviation Corporation): Amendment 39-6866. Docket No. 90-CE-38-AD. Final rule of priority letter AD.

Applicability: Models SA226-AT, SA226-TC, SA227-AT, and SA227-AC airplanes (all serial numbers), certificated in any category.

Compliance: Required as indicated in the AD, unless already accomplished.

To prevent rapid cabin decompression and passenger injury due to window breakage caused by ice shed from the propellers, accomplish the following:

(a) Prior to further flight unless accomplished in accordance with AD 90-12-14, modify the passenger seat adjacent to the cabin window at Station 181 on the right side of the cabin on those airplanes whose propellers turn counterclockwise looking forward, or on the left side of the cabin on those airplanes whose propellers turn clockwise looking forward, by accomplishing one of the following actions:

(1) Fabricate a placard using letters at least one inch in height on a contrasting background to read: "DO NOT OCCUPY THIS SEAT AT ANY TIME" and install this placard on the passenger seat closest to the cabin window at Station 181 of the passenger cabin in clear view of the occupants, or

(2) Remove the passenger seat closest to the cabin window at Station 181 of the passenger cabin.

(b) Within the next 30 calendar days after the effective date of this AD, unless accomplished in accordance with AD 90-12-14, reinforce the applicable cabin window located at Station 181 in the passenger cabin in accordance with either paragraph (b)(1) or (b)(2) of this AD. The restrictions required by paragraph (a) of this AD are no longer applicable when this modification has been accomplished.

(1) Add an inner pane in accordance with the instructions in Fairchild Aircraft Corporation Service Bulletins 226-56-004, revised January 8, 1990, or 227-56-004, issued July 26, 1989, as applicable, or

(2) Add a metal cover over the outside of the window in accordance with Fairchild Aircraft Corporation Kit 27K22005, Revision A, issued June 14, 1990.

(c) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished.

(d) An alternate method of compliance or adjustment of the compliance times which provide an equivalent level of safety may be approved by the Manager, Airplane Certification Office, Fort Worth, Texas 76193-0150 (facsimile number (817) 624-5988).

NOTE: The request should be forwarded through an FAA Maintenance Inspector, who may add comments and then send it to the Manager, Airplane Certification Office, Fort Worth, Texas.

Airworthiness Directive 90-14-01 supersedes priority letter AD 90-12-14.

This amendment (39-6866, AD 90-14-01) becomes effective on February 11, 1991, as to all persons except those persons to whom it was made immediately effective by priority letter AD 90-14-01, issued June 29, 1990, which contained this amendment.
