Compliance required within the next ten hours' time in service after the effective date of this AD, unless already accomplished. To prevent fuel valve inner port leakage, accomplish the following: I. Perform the following checks: 1. Fill all fuel tanks to capacity. 2. Actuate the fuel selector valve quick drain handle a minimum of three (3) times. Insure that the handle is actuated through its full travel and release slowly each time. 3. Start engine and run at a 1000 R.P.M. setting with electric fuel pump on. 4. Place fuel selector valve in the OFF position. 5. Continue to run the engine at 1000 R.P.M. until fuel has been exhausted and not to exceed the seven (7) minute duration. If fuel exhaustion occurs and the engine quits within the seven (7) minute running period, make an appropriate log book entry. The checks required by this AD may be performed by the pilot. For the requirements regarding the listing of compliance and method of compliance with this AD in the airplane's maintenance record, see FAR 91.173. II. If the engine continues to run for the full seven (7) minute period, replace the fuel selector valve with the appropriate serviceable fuel valve and repeat Paragraph I. An equivalent means of compliance with this AD must be approved by the Chief, Engineering and Manufacturing Branch, Federal Aviation Administration, Southern Region.
