AD Grob tail wheel
Geplaatst: 16 nov 2016, 07:33
Zie:http://ad.easa.europa.eu/blob/EASA_AD_2 ... 016-0228_1Applicability:
Grob G 109 and Grob G109B powered sailplanes, all manufacturer serial numbers.
Reason:
Occurrences were reported of broken pivots of the tail wheel mounting bracket. Subsequent
investigation attributed these events to corrosion and damage due to wear.
This condition, if not detected and corrected, could lead to loss of rudder control, resulting in
reduced control of the powered sailplane.
To address this potentially unsafe condition, Grob Aircraft AG issued Mandatory Service Bulletin
(MSB) 817-70 (hereafter referred to as ‘the MSB’ in this AD) to provide inspection and repair
instructions.
For the reasons described above, this AD requires repetitive inspections of the tail wheel mounting
bracket and, depending on findings, accomplishment of applicable corrective action(s).
