All Piper PA-18 and PA-19 (Super Cub) aeroplanes must have the fuel primer line—and the wheel brake hydraulic line if it currently passes behind the exhaust—re-routed away from the muffler and clamped to the firewall per Piper Service Letter No. 213.

Owners/operators and maintenance personnel must complete this work within 25 hours TIS after 31 March 1985 to prevent contact with the muffler and reduce the risk of an in‑flight fire.

Amdt 1

Fuel Primer and Hydraulic Lines - Re-Routing 4/85 DM

Applicability: All models.

Requirement: 1. To prevent contact with the exhaust muffler, re-route fuel primer line, and wheel brake hydraulic line if necessary, to ensure that they do not pass behind the muffler.

Using clamps, secure the lines to the firewall - refer to Piper SL No. 213 for fuel primer line clamping instructions.

Note: FAA AD 53-24-4 refers.

Compliance: Within 25 hours time in service after 31 March 1985.

Background: This Directive has been amended to combine the intent of Piper SL No. 213 and FAA AD 53-24-4 into a single requirement. Re-routing, as applicable, of the fuel primer line and wheel brake hydraulic line is necessary to preclude the possibility of an in- flight fire.
