ATA 25 – Crew Seat Armrest Stop Pin
C90GT; B200GT/B200GTC; B300 Series
Crew seat armrests are subject to abuse as it is often used as a prop to get in and out of the crew seat. The mechanism was not designed for this purpose and the result is damage to the MS171538 split pin which it is there as a stop when it is used as an armrest (see photo, below).
Engineering has approved the use of a solid pin to provide a more robust installation; however, it is still recommended that the armrest be folded up and out the way while entering or existing the crew position and not used as a prop. The part number of the solid pin is MS16556-833, available from Textron Aviation Parts and Distribution.
This change started at FL-1176, FM-79, BY-347, LJ- 2160 and on. For aircraft with this installation, you will bond the pins into the armrest frames using Loctite 609.
