SUPPLEMENTARY INFORMATION:  

REGULATORY TEXT:   83-22-07 BRITISH AEROSPACE: Amendment 39-4766. Applies to British Aerospace Model 3101 (all serial numbers) airplanes certificated in any category.

Compliance: Required prior to further flight, unless already accomplished.

To reduce the possibility of development of short period pitch oscillations, accomplish either paragraphs a) or b) as follows:

a) Placard the airplane and modify the AFM as follows:

1) Fabricate and install in full view of the pilot a temporary placard using letters of minimum .10 inch in height which states: "FLIGHT IN ICING CONDITIONS PROHIBITED. MAXIMUM PERMITTED FLAP ANGLE IS 20 DEGREES." and operate the airplane in accordance with these limitations.

2) Add the following information to page 37, Section 5 of the AFM:

"Landings must be made with no more than 20 degrees of flap selected. Increase approach speed by 10 knots."

3) Add the following information to pages 45 and 47, Section 5 of the AFM:

"Landings must be made with no more than 20 degrees of flap selected. The scheduled field lengths are increased by 20 percent."

4) Insertion of a copy of this AD in front of the pages specified in paragraphs a)2) and a)3) above satisfies the requirements of these paragraphs.

5) The requirements of paragraphs a)1) through a)4) of this AD may be accomplished by the holder of a pilot certificate issued under Part 61 of the Federal Aviation Regulations (FAR) on any airplane owned or operated by him. The person accomplishing these actions must make the appropriate aircraft maintenance record entry as prescribed by FAR 91.173. or

b) Incorporate British Aerospace Modification JM7328, Part B, in accordance with the accomplishment instructions of British Aerospace Service Bulletin 27-A-JM7328, Revision 2, dated September 12, 1983.

1) Until AFM revisions are received and incorporated, make the following amendments in the AFM of the modified airplane:

A) In Section 2 of page 3, the aft limit of the center of gravity envelope is moved from 228 inches aft of datum to 226 inches aft of datum at all weights.

B) In Section 5 of page 31, the weight limited both engines operating enroute climb speed is increased to the following values:


AIRPLANE WEIGHT
(THOUSANDS OF POUNDS)	AIRSPEED
(KNOTS IAS)
10	109.0
11	114.5
12	119.5
13	124.3
14	129.1
14.55	131.8

2) Following incorporation of British Aerospace Modification JM7328, Part B, perform a flight test in accordance with British Aerospace Flight Test Schedule FTS 397/JM dated August 2, 1983, as referenced in British Aerospace Service Bulletin 27-A-JM7328, Revision 2, dated September 12, 1983. This flight test is to be accomplished either by a British Aerospace factory test pilot or under the supervision of an FAA test pilot, or by a British Aerospace factory approved pilot.

c) An equivalent means of compliance with this AD may be used, if approved, by the Manager, Aircraft Certification Staff, AEU-100, Europe, Africa and Middle East Office, FAA, c/o American Embassy, Brussels, Belgium.

This AD supersedes AD 83-14-11, issued by priority letter dated July 19, 1983.
This amendment becomes effective on November 10, 1983.
