Airworthiness Directive · Amendment 39-18152 · Starting
GROB-WERKE Airplanes
This AD applies to GROB-WERKE Model G115EG airplanes, all serial numbers through 82323/E, and Model G120A airplanes, all serial numbers through 85063, certificated in any category.
We are superseding Airworthiness Directive (AD) 2014-26-04 for certain GROB-WERKE Models G115EG and G120A airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a defective starter solenoid. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the actions in paragraphs (f)(1) through (f)(3) of this AD:
(1) Within the next 30 days after February 9, 2015 (the effective date retained from AD 2014-26-04), inspect the starter following Part A of the Accomplishment Instructions in GROB Aircraft Service Bulletin No. MSB1078-196, dated July 14, 2014; GROB Aircraft Service Bulletin No. MSB1078-196/1, dated December 1, 2014; GROB Aircraft Service Bulletin No. MSB1121-144, dated July 14, 2014; or GROB Aircraft Service Bulletin No. MSB1121-144/3, dated February 20, 2015, as applicable.
(2) If any damage is found on the starter during the inspection required in paragraph (f)(1) of this AD, before further flight, replace the starter with a serviceable part. Do the replacement following Part A of the Accomplishment Instructions in GROB Aircraft Service Bulletin No. MSB1078-196, dated July 14, 2014; GROB Aircraft Service Bulletin No. MSB1078-196/1, dated December 1, 2014; GROB Aircraft Service Bulletin No. MSB1121-144, dated July 14, 2014; or GROB Aircraft Service Bulletin No. MSB1121-144/3, dated February 20, 2015, as applicable.
(3) Within the next 100 hours time-in-service after June 16, 2015 (the effective date of this AD), install a starter relay following Part B of the Accomplishment Instructions in GROB Aircraft Service Bulletin No. MSB1078-196/1, dated December 1, 2014, or GROB Aircraft Service Bulletin No. MSB1121-144/3, dated February 20, 2015, as applicable.
Actions done before June 16, 2015 (the effective date of this AD) following the Accomplishment Instructions specified in GROB Aircraft Service Bulletin No. MSB1121-144/1, dated January 12, 2015; or GROB Aircraft Service Bulletin No. MSB1121-144/2, dated February 5, 2015, as applicable, are considered acceptable for compliance with the corresponding actions specified in paragraphs (f)(1) through (f)(2) of this AD.
