Heavy Check!

Growing up I thought that that an aircraft lasted "forever". As a member of the traveling public, some of us think that a plane is like the family car. Check the oil, the tires and change/add fluid as necessary. On occasion, we do a monthly check on the car and get our inspections done yearly. But with an aircraft, maintenance on these winged beauties are an on going process. Currently, one of our Dash-8-100's, N805WP, is in ourhanger for a "C" Check or a heavy inspection.

N805WP "Holomua"  in the hanger

The check is very extensive. Every portion of the aircraft is scrutinized. From Nose to tail. Nothing is overlooked. Rivets that hold the skin flaps are inspected. Aircraft interiors are taken out. Items needing repair or replacement are addressed. Avionics inspects and test all the instruments

#1 engine removed. Leading edge boots removed. Her seats on the hanger floor, 805's heavy check in progress

In a rarely seen area are the control cables that are linked to the control column in the cockpit. When a pilot turns the the controls one direction or another or pushes or pulls back, these cables respond by moving the control surfaces of the aircraft in relation to the input

 The cables run the length of the aircraft. Most aircraft have this type of configuration. The exception would be those aircraft that are "fly-by-wire" where electronic signals control the movements of the control surfaces

Looking thru the #1 engine mounting

Panels to the aircraft's rudder actuators are open and the elevator boots are missing

Looking thru the open cargo door, we can see the exposed pressure bulkhead and ducts.
The black marks on the wall to the left are from the constant scrapes of bags being placed in the hold

looking forward from the cargo door we see the cabin side panels removed for cleaning and inspection
Overhead cargo bins are still in place with the rest of the cabin covered and taped. Side panel installation is clearly visible as is the ceiling. The large opening is the under wing emergency exit

Here's another view of the cabin looking from the front to the rear cargo door area. Still alot of work to be done

 Main cabin door area with the galley covered. This aircraft is st to come out of the hanger on 01 Nov. Still alot more to be done. I look forward to dispatching this aircraft again when she is done with the check. 805 is one of my favorite aircraft's
