The airworthiness directive
59-26-02 PIPER: Applies to PA-24 and PA-24 "250" Airplanes Serial Numbers 24-1 To 24-1373 Inclusive.
Compliance required by January 15, 1960.
To prevent clogging, the two fuel cell vent tubes which are located under the wings shall be modified in the following manner:
Measure a distance of 1/2-inch down from the bottom of the wing skin along the forward side of each protruding vent tube. At this point, cut the tube off at a 45-degree angle to the bottom skin so that the end of the tube remains square.
(Piper Immediate Action Service Bulletin No. 180 covers this subject.)
