The airworthiness directive

48-03-03 PIPER: Applies to PA-11 Aircraft Serial Numbers 11-1 Through 11-301, and 11-1350 Through 11-1400, Except Serial Numbers 11-233, 11-243, 11-261, 11-266, 11-281, 11- 296, and 11-300.

Compliance required by April 1, 1948.

In order to prevent engine malfunctioning due to insufficient fuel flow when less than 5 gallons of fuel are in the wing tank and the airplane is operated in prolonged glides and dives, a header tank (Piper P/N 10725) must be installed in the fuel system. Until the header tank is installed, avoid prolonged glides and dives when less than 5 gallons fuel are in the main tank. (Piper Service Bulletin No. 99 dated July 29, 1947, covers this subject.)
