Definition

Just trying to tap into the wealth of knowledge out there.

Anyone know the official definition of Line maintenance. Ive looked all over the 145 and part 66 but cant find the definition although its mentioned a lot.

Any help is good help.

line maintenace is basically maintenance on the go(live) or tasks done during turnarounds or overnight on the ramp/gate,it doesnt really need to be defined

I agree. Line maint is the work carried out to keep the thing flying. But where is the line drawn.

I have an authorisation from an authority to carry out line maintenance on two private catagory aircraft (CRJ). but what is "line"

I have been in situations where ive changed landing gear on the ramp. This was at a line station and done by line guys. In my opinion thats not line maintenance but it does fall into the defect rectification side of things so what is the official rule or is it such a grey area that people just cant commit.

I have also been at a line station that used to do scheduled engine changes. When the CAA arrived they said that an engine change may be carried out but due to the scope of work for the particular station it must only be on a casualty bassis and not scheduled.

So what is considered line maintenance?

Try EASA Part 145.A.10 - Scope.
The AMC says :-

"AMC 145.A.10 Scope
1. Line Maintenance should be understood as any maintenance that is carried out before flight to ensure that the aircraft is fit for the intended flight.
(a) Line Maintenance may include:
�� Trouble shooting.
�� Defect rectification.
�� Component replacement with use of external test equipment if required. Component replacement may include components such as engines and propellers.
�� Scheduled maintenance and/or checks including visual inspections that will detect obvious unsatisfactory conditions/discrepancies but do not require extensive in depth inspection. It may also include internal structure, systems and powerplant items which are visible through quick opening access panels/doors.
�� Minor repairs and modifications which do not require extensive disassembly and
can be accomplished by simple means.
(b) For temporary or occasional cases (AD's, SB's) the Quality Manager may accept base maintenance tasks to be performed by a line maintenance organisation provided all requirements are fulfilled as defined by the competent authority.
(c) Maintenance tasks falling outside these criteria are considered to be Base Maintenance."
Hope this helps
