REGULATORY TEXT:  
88-11-07 CESSNA: Amendment 39-5971. Final copy of priority letter AD. Applicable to Model S550 and 552 airplanes, Serial Numbers S550-0001 through S550-0153, and 552-0001 through 552-0017, certificated in any category.

Compliance is required prior to further flight after the effective date of this amendment, unless already accomplished.

To prevent loss of a flap panel, accomplish the following:

A. Visually inspect the inboard lower surface of each of the four flap panels to verify that each panel has the three required drain/vent holes, and verify that these holes are unobstructed. If all required holes are installed and unobstructed, no further action is required.

NOTE: The drain holes are 3/16-inch diameter and are located approximately one inch outboard of the inboard end of the lower surface of each flap panel. (Reference: Maintenance Manual, Section 5-10-01, "Hour and Calendar Inspection Requirements," Item Z(6), "Flaps;" or Cessna Service Letter SLAS550-57-01, dated May 20, 1988.)

B. If any drain/vent hole in any flap panel is not present or is found to be obstructed, repair or replace prior to further flight, in accordance with Cessna Service Bulletin SBS550-57-5 (for Model S550 series airplanes), dated May 24, 1988; Cessna Service Bulletin 552-57-5 (for Model 552 series airplanes), dated May 24, 1988; or an FAA-approved method.

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, Wichita Aircraft Certification Office, FAA, Central Region.

All persons affected by this directive who have not already received the appropriate service documents from the manufacturer, may obtain copies upon request to Cessna Aircraft Company, Citation Jet Marketing Division, Technical Services Department, Attention: Roger Hatfield, P.O. Box 7706, Wichita, Kansas 67277. These documents may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or at FAA, Central Region, Wichita Aircraft Certification Office, 1801 Airport Road, Room 100, Wichita, Kansas.

Amendment 39-5971 was effective earlier to all recipients of Priority Letter AD 88-11-07, issued May 24, 1988.

This amendment, 39-5971, becomes effective July 21, 1988.
