JSa, and other wannabies.
I can't stress this too much. Do yourselves a really big favour and record 'all' your hours. Have a look at a pilots log book as an example. This is what is now happening in engineering and maintenance. Multi licenced engineers with 30+ years experience are being asked for proof of currency on type. We don't keep logs like pilots do, never been a real concern.
Now it is!!
A prop or an engine might come in a crate and need some assembly as well. Preparing the engine change cradle. This is part of an LAE's job, as he is responsible for it. Claim it.
Looking up an MM, IPC or an SB, all part of an LAE's job.
I once flew with Ray Miller in PNG. He was proud that he was in the top few at 33,000 hours. 16,000 alone on DC3's.
Work out 40hrs a week for 48 weeks a year working in a hangar and it adds up quickly.
Get whatever qualifications you can and work up from there. Having an A licence is better than having nothing. Some are dissapointed in the whole field and leave. Better to know sooner than later if the job suits you.
In reality experience is what a genuine employer wants, not licences with the ink still wet. Be nice if you have it all recorded!
Good lucks......
