Within the last few weeks at Duncan Aviation, we’ve had discussions about tire changes on Bombardier Learjet* and other make/model aircraft and what criteria to use when replacing a tire. It sounds pretty simple, but there is a lot of information you should be aware of.
There are aircraft maintenance providers that will replace your tire using only the CMM (Component Maintenance Manual) and have the 8130 state that as their only reference data. But when was the last time you looked in your AMM (Aircraft Maintenance Manual) to confirm that this met all the stated requirements?
The AMMs for Learjet 31, 35, 36 & 60* Series aircraft call out the replacement of ALL the self-locking nuts when re-assembling the wheel halves. Yet the Learjet 20 & 55* series do not, at least not at this time.
Are you aware of the criteria used on your last tire change?
We have seen other OEMs place other requirements, such as eddy current and Chapter 5 Requirements, on wheel and tire assemblies over and above what the CMM calls out.
At the end of the day, who is responsible for ensuring ALL requirements are met when installing ANY part on an aircraft? That’s right… the one doing the installation. In most cases, that is probably YOU.
When sending in a wheel and tire assembly for a tire change, please state which aircraft maintenance manual you would like us to reference to ensure we comply with all the requirements that you, as the installer, will need.
