Plain English Summary

1/10 complexity

What this does: This is a safety rule for owners of Beagle B121 Pup aircraft. It requires installing a small drain hole in the bottom of the plane's rudder (the vertical tail fin).

Who it affects: Owners and operators of all Beagle B121 Pup model aeroplanes.

Why it matters: Without a drain hole, moisture can get trapped inside the rudder and cause corrosion (rust) or structural damage. This simple modification lets water escape, preventing deterioration that could affect flight safety.

What must be done: A suitable drain hole must be added to the lower rudder area to allow moisture to drain out.

Deadline: The work had to be completed within 100 hours of flying time after 28 April 1972.
