Maintenance Releases and Tyres
Hi, just going over MR requirements and having a bit of a search through casa documents relating to MRs and tyres but there’s not a lot of advice easily locatable.
Hope someone might be able to shine some light on the situations below:
After completing a daily inspection and finding a
tyre is flat or very low and causes concern is it
appropriate to put it in part 2 of a maintenance
release as requiring attention?
How tiny is too tiny in terms of what to put on an
MR as requiring attention?
Commonsense says that a tyre without tread
increases risk of hydroplaning on wet runway
surfaces and also reduces friction and stability on
the ground. Would this be something to be noted
on an MR?

If the tyre is low the pilot is allowed to inflate it to the pressure in the POH.
A determination to be decided by a LAME if it looks worn, remember it is not visible tread depth that determines serviceability unlike motor tyres.
Contrary to what is espoused by some, any defect or concern re serviceability must be entered on the M/R and brought to the attention of the owner or the organisation hired from.

Part 2 is for defects that could cause an airworthiness issue for the aircraft. By entering it, it may not render the aircraft unserviceable, but act as an advisory, UNLESS the defect affects the proposed next operational flight.
EG> your tyre is low/flat. Would it affect a takeoff and cause a landing mishap. Yes. But can it be easily rectified without professional labour or specialist equipment, then don't enter it. Just get a fuel truck to inflate it with their air compressor. BUT if you needed nitrogen, a nitrogen bottle & regulator [thus a mechanic] then YES, put it on the MR.
Generally anything requiring tools, professional labour, and may deem the aircraft unsafe for night flight or navigational tasks, then Yes.
