INSPECTION OF ELEVATOR PUSH RODS FOR CORROSION AND POSSIBLE ROD REPLACEMENT
CANCELLED - Superseded by EASA AD 2020-0138
Applicable to GROB 103 series gliders from serial no 3544 to 3878 (inclusive). GROB Service Bulletin TM 315-34 outlines the requirement to inspect elevator push rods part no's 103A-4244 and 103A-4694 for corrosion and or trapped moisture. GROB have indicated that this Service Bulletin only applies to the "Acro" model of the G103 however G.F.A. has elected to request the inspection of all G 103 gliders due to history showing that GROB may have fitted the suspect parts into non Acro serial no's. Any push rod that has one end open and the other closed up is likely to trap moisture and suffer from internal corrosion. Vertical push rods are the worst since they can collect moisture at the bottom end from condensation as well as direct penetration (rain etc). Service Bulletin TM 315-34 forms part of this Airworthiness Directive.
