1. 17.5x5.75-8, 12PR, 210MPH, P/N 038-627, S/N 3224A-XXXXX, and

2. 18x5.5, 10PR, 210MPH, P/N 033-631, S/N 3215A-XXXXX through 3217A-XXXXX.

These tires are eligible for, but not limited to use on, all Gates Learjet models and Fairchild Swearingen Model SA226-TC airplanes.

Compliance: Required prior to next takeoff, unless already accomplished.

To avoid tread loss and possible subsequent tire failure, accomplish the following:

Remove the applicable part number and serial number BF Goodrich tires from the aircraft and either destroy them or return them to BF Goodrich for destruction. Cutting the tire carcass is an approved means of destruction.

NOTE: The serial numbers of the tires are interpreted as follows:

This amendment becomes effective on February 21, 1984, to all persons except those to whom it has already been made effective by priority letter from the FAA dated December 23, 1983, and is identified as AD 83-26-03.
