CATP - are you saying that you passed all the ATPL(H) exams, but didn't then obtain a CPL(H) or IR(H) within 36 months of having completed the exams?
The
old LASORS 2010 requirement for the CPL(H) and IR(H) was:
D6.6 INSTRUMENT RATING REQUIREMENTS
It is not mandatory for a QSP(H) to complete an Instrument Rating before being issued with a CPL(H).
An applicant for an IR(H) is required to complete the requirements in accordance with Section E2.
QSPs should note that JAR-FCL 2 requires both a CPL(H) and IR(H) to be obtained within the 36 month Acceptance Period of the ATPL(H) examinations to maintain ATPL(H) theory credit for the subsequent issue of an ATPL(H).
However, it has been agreed that a QSP(H) will not be subject to this requirement. Whilst the 36 months Acceptance Period will still apply to the issue of a CPL(H), an IR(H) can be obtained at any time up to 3 years from the date of the last flight in a military helicopter, and still retain ATPL(H) theory credit.
The exam acceptance periods under part-FCL can be found in FCL.025 para (c) in CAP 804 Section 4 Part A Page 3 (.pdf page 119 / 794).
