Hi, if an A/C is in maintenance IE A check etc for an extended period of time do you still have to carry out the parking requirements?
This has come about with A/C going into long term parking due Covid
Cheers

Hi,
Actually it is a good question. AMM says that: "An aircraft in heavy maintenance (e.g. scheduled check, working party or repair after an incident) is not in parked or stored condition. It is necessary to define and apply an adapted preservation procedure." It is quite an obscure wording.
So it seems like it is up to operators CAMO to define and apply this adapted preservation procedure.
I will be glad if someone can share more detailed information on this topic.

Here's Boeing's explanation, an extract from the B747 AMM:
Isn't airplane "in storage" condition during repair period?
No. This statement is not right. Even through the airplane is in maintenance/repair condition, not all airplane systems are operated through this time period. This is a partial storage situation. Boeing recommend airlines to complete all storage tasks for no operating (not in repair) systems.

In the earlier days of the RB211 there was a schedule to power run and change scavenge filters after only a few days of engines being static; reason: the carbon deposits lining some oil passage ways, mostly near the hotter sections, would detach and clog the filter leading to an IFSD.
An improved filter area and oil spec largely cured the problem.
It would be standard practice, if the aircraft was weight on wheels to schedule a rotation of same to avert flat spots.

I'm sorry. I'm new to the forum. I tried to post a new thread, but it keeps telling me that I'm not allowed to post a URL until I put in 10 posts. I did not submit a URL, so I go around in circles. I just have one question. The A320 Nose landing Gear. There is a drag link that attaches to the Strut. Is it a Spherical / Ball joint there?
Thanks,
Le

Hi, Maybay
Indeed drag strut (aka forestay on A320) has spherical bearing at attachment to the shock strut assy. I'd attach picture but "I'm not allowed to post a URL until I put in 10 posts".

Acie,
Thank you so much for your response ! I've always wondered about it since at the top of the forestay there is a universal joint. The spherical joint is needed so that the forestay will not bind up during retraction and deployment. I figured this out using the Gruebler's Count formula for mechanisms. You made my day, thank you !!
