Where's the risk!
Because not everyone's as good a pilot as you, and I can't change the rules to suit you, I have to comply with CASA's view, and when you sell the aircraft to someone else who does have that failure, they won't be as forgiving as you,
Nor the maintainer who then reports me to CASA,
Everyone does this internal risk assessment on the possible outcome of a failure of a component, would it be mad to let go on a single engine, but ok on a twin, would the back up instrument save me, would it cause a fuel leak, how bad, so many variables.
CASA stipulate when using Sched 5, manufacturers Data must be used and that includes components.
The manufacturers data includes all SB's ect. TCM have 5 categories of SB/SL etc. that are referred to.
When the SB states quite clearly, that mags MUST be done at 4 years, I do.
Again, everyone seems happy to do the 500hr, but omit the 4 yearly. It's
The same Doc.
