Plain English Summary

2/10 complexity

This Airworthiness Directive requires owners/operators of Robin HR 100/250 and HR 100/285 aeroplanes with retractable landing gear to replace the inlet and outlet pipes of the retractable‑gear hydraulic pump in accordance with Avions Pierre Robin Service Bulletin No. 148 (26 April 1996). Compliance is due at the next scheduled maintenance and thereafter at every second disassembly of the pipes; owners/operators pay for and must arrange the work. The measure responds to cracking of tubing flares caused by frequent removal and re‑tightening of tube fitting nuts.
