AD 87-21-05 Placard – Spins
October 13, 1987
This AD applies to all 150s, A150s, 152s, and A152s modified by STC SA4795SW.
This AD is to assure that airplanes modified with the Del Air 0-320/0-360 engine replacement STC are operated within approved center of gravity limits and approved operating limitations. The STC placards must be removed and new placards installed. The airplanes will be operated in the Utility Category, and the new placards state “INTENTIONAL SPINS ARE PROHIBITED.”

Compliance: Required within the next 50 hours time-in-service after the effective date of this AD, unless already accomplished.
To assure operation of the airplane within the approved center of gravity (CG) limits and approved operating limitations, accomplish the following:
(a) For Model 150, 150 A/B/C, airplanes accomplish the following:
(1) Remove the placard required by STC SA4795SW which states the category and weight limits and begins with the words “THIS AIRPLANE MAY BE OPERATED . . .” The placard should be located on the right hand door post.
(2) Fabricate a placard with the following statement using letters with a minimum height of 1/8 inch: “NOT APPROVED FOR SPINS.” Install this placard in clear view of the pilot on the airplane instrument panel.
(3) Operate the airplane in the Utility Category in accordance with the placard and the operating limitations for center-of-gravity and maximum weight as specified in the original weight and balance data for an unmodified airplane.
NOTE: Compliance with Airworthiness Directive 86-15-07 does not relieve compliance with this AD for Models 150, 150A/B/C airplanes.
(b) For Model A150 K/L/M airplanes, accomplish the following:
(1) Remove the placard required by STC SA4795SW which states the category and weight limits and begins with the words “THIS AIRPLANE MAY BE OPERATED . . .” The placard should be located on the right hand door post.
(2) Fabricate the temporary placard detailed in Figure 1. of this AD, marking it with the statement as shown and install it in clear view of the pilot on the instrument panel over the existing maneuver placard.
(3) Operate the airplane in the Utility Category in accordance with the placard and the operating limitations for center-of-gravity and maximum weight as specified in the original weight and balance data for an unmodified airplane.
(c) For Model A152 airplanes, accomplish the following:
(1) Remove the placard required by STC SA4795SW which states the category and weight limits and begins with the words “THIS AIRPLANE MAY BE OPERATED . . .” The placard should be located on the right hand door post.
(2) Fabricate the temporary placard detailed in Figure 2. of this AD, permanently marking it with the statement as shown and install it in clear view of the pilot on the instrument panel over the existing maneuver placard.
(3) Operate the airplane in the Utility Category in accordance with the placard and the operating limitations for center-of-gravity and maximum weight as specified in the original weight and balance data for an unmodified airplane.
(d) For Model 150 D thru M and 152 airplanes, accomplish the following:
(1) Remove the placard required by STC SA4795SW which states the category and weight limits and begins with the words “THIS AIRPLANE MAY BE OPERATED . . .” The placard should be located on the instrument panel over the existing maneuver placard.
(2) Fabricate the placard detailed in Figure 3. of this AD, permanently marking it with the statement as shown and install it in clear view of the pilot on the instrument panel over the existing maneuver placard. Alternatively, this placard may be obtained from Aircraft Conversion Technologies, Inc., 1410 Flight Line Drive, Lincoln, California 95648.
(3) Operate the airplane in accordance with the placard.
(e) Installation of the placards required by this AD may be accomplished by the owner/operator on any airplanes which are not used under FAR Part 121 or 135. The person accomplishing these actions must make the appropriate airplane maintenance record entry per FAR 43.9 and 91.173.
(f) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished.
(g) An equivalent means of compliance with this AD may be used if approved by the Manager, Aircraft Certification Division, FAA Southwest Region, Fort Worth, Texas 76193-0100; telephone (817) 624-5100.
All persons affected by this directive may obtain copies of the document(s) referred to herein upon request to J&S Engineering, 222 W. Turbo Drive, San Antonio, Texas 78216; or may examine the document(s) referred to herein at FAA, Office of the Regional Counsel, Room 1558, 601 East 12th Street, Kansas City, Missouri 64106.
