| Requirement: | Inspect the engine air intake by-pass flap in accordance with the instructions contained in Robin Aviation Service Bulletin Number 174 dated 29 November 2000, as in force at the commencement of this AD.The pilot in command, other than a student pilot, may carry out the initial engine air intake inspection. Compliance is recorded by entering in the Aircraft Log Book; “AD/ROBIN/36 Amdt 1 carried out”. Any discrepancy disclosed in carrying out the inspection shall be recorded in the “Maintenance required” column of the aircraft maintenance release or equivalent document.Note: New Zealand Civil Aviation Authority AD DCA/R2000/31A refers. |
| Compliance: | Before further flight, unless previously accomplished, and thereafter at intervals not to exceed 100 hours’ time in service or one year, whichever is the earlier. |
| This AD commences on 29 March 2019. | |
| Background: | There have been several reports of the air box sealing felt which is glued and riveted on the by-pass flap causing obstruction of the carburettor, preventing the engine from delivering its maximum power. As a consequence, the performance of the aeroplane, notably during take-off, may be significantly degraded.This condition, if not corrected, could lead to an uncommanded in-flight engine shut-down, possibly resulting in loss of control of the aeroplane. |
| Amendment 1 of this AD removes from the applicability certain aircraft models which are now covered by EASA AD 2014-0225, amends the compliance note to reflect DCA/R2000/31A, and provides further background information in relation to this issue. |
