Searbelts
I do have a concern about these!
Having purchased an aircraft which used to be looked after by a reputable maintenance company last year. The aircraft is nearly 30 years old, the seatbelts were the original ones despite the fact the manual says they are supposed to be lifed at 10 years. Fair enough you might say to run on condition. Except the pax seatbelt was attached to the airframe by a tiewrap, and when the belts were removed (to be replaced) the stitching fell apart.
Now maybe the owners had a say in not replacing them at the last check, but someone released that aircraft to service.
Luckily we didn't have to test the old belts in anger. Now we have fitted ones that aren't lifed.
