The Main Entry Door on Hawker aircraft is durable and very reliable. And by adding these basic operational measures, you will ensure years of continued problem-free service.
1) Door Stay with loose rivets, 2) Entry door lever and shaft, 3) Door Maintenance Cables
In addition to normal door lubrication, the top and bottom door stay and hinge shaft linkages deserve some attention. Make it a point to keep them lubricated and clean.
Door Support Cables
The use of door support cables during servicing and maintenance will go a long way in reducing wear in the door stays and hinge shafts.
One Person at a Time
The policy of allowing only one passenger on the steps while entering or exiting the aircraft will also help in reducing wear.
There are several areas on the Main Entry Door where we have found wear, these include elongated bolt holes in the entry door lever to the entry door shaft and loose rivets in the door stay top and bottom tubes and fork end. Repairs for these items can be found in the Structural Repair Manual. Loose rivets and elongated bolt holes can be readily detected by applying weight to the last step and observing the amount of movement and its location. Prompt detection and repair will reduce the likelihood of costly parts replacement.
