Compliance required prior to July 1, 1947.
Inspect the rivets of the forward end of the elevator control push-pull tube in front of the instrument panel for size, looseness and replacement as necessary. If the installation has been made with four 5/32-inch diameter rivets, replace with six 3/16-inch rivets (3 on each side evenly spaded). If four 3/16-inch diameter rivets are already installed and looseness exists, replace the loose rivets and install two additional 3/16-inch rivets (one on each side evenly spaced).
