You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Service Bulletin Reference (f) The term “service bulletin,” as used in this AD, means the Accomplishment Instructions of Goodrich Service Bulletin 25-343, Revision 3, dated January 12, 2007. Replacement, or Inspections and Corrective Action (g) Within 36 months after the effective date of this AD, do the actions specified in paragraph (g)(1) or (g)(2) of this AD in accordance with the service bulletin. (1) For airplanes equipped with any Goodrich evacuation system identified in paragraph (c)(1) or (c)(2) of this AD: Replace the shear-pin restraints with new restraints. (2) For airplanes equipped with any Goodrich evacuation system identified in paragraphs (c)(3) through (c)(27) of this AD: Do an inspection to verify the manufacturing lot number of the shear-pin restraint. A review of airplane maintenance records is acceptable in lieu of this inspection if the manufacturing lot number of the shear-pin restraint can be conclusively determined from that review. (i) If a manufacturing lot number from 3375 through 5551 inclusive is found, before further flight, replace the shear-pin restraint with a new restraint. (ii) If a manufacturing lot number from 3375 through 5551 inclusive is not found, do a general visual inspection of the shear-pin restraints for discrepancies (i.e., corrosion, security of pin retainer/label, overall condition, and lack of play). If any discrepancy is found, before further flight, replace the shear-pin restraint with a new restraint. Note 1: For the purposes of this AD, a general visual inspection is: “A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to ensure visual access to all surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.” Parts Installation (h) As of the effective date of this AD, no Goodrich evacuation system with a part number and serial number identified in paragraph (c)(1) or (c)(2) of this AD may be installed on any airplane, unless the shear- pin restraints have been replaced with new restraints in accordance with paragraph (g)(1) of this AD. (i) As of the effective date of this AD, no Goodrich evacuation system with a part number and serial number identified in paragraphs (c)(3) through (c)(27) of this AD may be installed on any airplane, unless the shear-pin restraints have been inspected and found acceptable in accordance with paragraph (g)(2) of this AD. Credit for Actions Done Using Previous Service Information (j) Replacements and inspections done before the effective date of this AD in accordance with Goodrich Service Bulletin 25-343, dated October 15, 2003; Revision 1, dated January 31, 2005; or Revision 2, dated October 11, 2006; are acceptable for compliance with the requirements of paragraph (g) of this AD. Alternative Methods of Compliance (AMOCs) (k)(1) The Manager, Los Angeles Aircraft Certification Office, FAA, has the authority to approve AMOCs for this AD, if requested in accordance with the procedures found in 14 CFR 39.19. (2) To request a different method of compliance or a different compliance time for this AD, follow the procedures in 14 CFR 39.19. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. Material Incorporated by Reference (l) You must use Goodrich Service Bulletin 25-343, Revision 3, dated January 12, 2007, to perform the actions that are required by this AD, unless the AD specifies otherwise.

This AD results from several reports of corroded shear-pin restraints that prevented Goodrich evacuation systems from deploying properly. We are issuing this AD to prevent failure of an evacuation system, which could impede an emergency evacuation and increase the chance of injury to passengers and flightcrew during the evacuation.
