Plain English Summary

2/10 complexity

This directive requires owners and operators of specific Fletcher FU-24 agricultural aircraft to regularly inspect the tail section for dangerous cracks.

Who it affects: Anyone operating Fletcher FU-24 series planes with serial numbers below 120 that haven't been modified according to the manufacturer's Service Bulletin 58-1 (issued 12 September 1958).

What it requires: You must check the vertical fin (the upright tail section) ribs and skin for cracking at least every 200 hours of flight time.

Why it matters: Cracks in the tail structure can lead to structural failure and potentially cause the aircraft to crash. This is a safety-critical maintenance requirement to prevent accidents in these older aircraft models.
