What this directive does

This is an Airworthiness Directive (a mandatory safety notice) requiring owners of specific Piper aircraft to install a warning label near the fuel caps.

Who it affects

Owners and operators of Piper PA-23-250 aircraft (Aztec models) that have been fitted with Met-Co-Aire wing tip fuel tanks.

What you must do

Install a placard next to the wing tip fuel tank fillers that reads:

FILL OUTBOARD MAIN TANK FIRST, THEN FILL TIP TANK THEN RE-CHECK OUTBOARD MAIN TANK QUANTITY.

Why it matters

The directive ensures pilots fill fuel tanks in the correct sequence. Filling the tip tank before properly checking the main tank could lead to fuel starvation or dangerous weight distribution issues during flight.

When it had to be done

Within 100 hours of flying time after 30 June 1972 (note: this is a historical directive from 1972).
