Applies to all Model 747 and 757 series airplanes, certificated in any category. Compliance required as indicated, unless previously accomplished. To ensure proper passenger door operation during emergency evacuation, accomplish the following: A. Within 60 days after the effective date of this AD, in order to find defective passenger door emergency power reservoirs, inspect the serial numbers of those reservoirs installed on airplanes in accordance with Boeing Service Bulletin 747-52A2201 (for Model 747 airplanes) or 757-52A0022 (for Model 757 airplanes), both dated September 15, 1986, or later FAA-approved revisions or check the applicable airplane records for those passenger door emergency power reservoir serial numbers listed in H. R. Textron Service Bulletin 803300-52-05 dated September 15, 1986, or later FAA-approved revisions. 1. If the serial number is not one listed in H. R. Textron Service Bulletin referenced above, no further action is necessary. 2. For any reservoir on which the serial number matches one listed in the H. R. Textron Service Bulletin referenced above, determine if the reservoir is fully charged. If any discharged emergency power reservoir is found, replace or modify before further flight in accordance with the applicable Boeing Service Bulletin referenced above. NOTE: These units may have been installed on Boeing Models 747 and 757 series airplanes other than those listed in the Boeing Service Bulletins referenced above. 3. For each emergency power reservoir installed on an airplane with a serial number listed in H. R. Textron Service Bulletin 803300-52-05, dated September 15, 1986, determine on a daily basis that the reservoir is fully charged. This daily procedure may be discontinued once the reservoir is modified in accordance with the applicable Boeing Service Bulletin referenced above. If any discharged emergency power reservoir is found, replace or modify before further flight in accordance with the applicable Boeing Service Bulletin referenced above. B. Within 15 months after the effective date of this AD, modify all emergency power reservoirs listed in H. R. Textron Service Bulletin 803300-52-05, dated September 15, 1986, in accordance with the applicable Boeing Service Bulletin referenced above. C. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region. D. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base for the accomplishment of inspections and/or modifications required by this AD. All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to the Boeing Commercial Airplane Company, P.O. Box3707, Seattle, Washington 98124-2207. These documents may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington.
