What are 3 things that need to be checked when performing key and key screw inspection?
Key and Key Screw Inspection As mentioned, there should be no movement between the wheel and the keys. The bolts should be checked for security, and the area around the keys should be inspected for cracks. There is also a limitation on how worn the keys can be since too much wear allows excessive movement.
What is inboard wheel?
Most notably, the inboard wheel is designed to accept and drive the aircraft brake rotors, which are mounted onto both main wheels. There are many methods for bolting the inner wheel half to the brakes. Regardless, this feature is the simplest way to distinguish the inner half from the outer half of the aircraft wheel.
What is inboard wheel half?
Inboard Wheel Half to engage and rotate the rotors of a disc brake. Both wheel halves contain a bearing cavity formed into the center that accepts the polished steel bearing cup, tapered roller bearing, and grease retainer of a typical wheel bearing set-up.
What is a Downlock switch?
The downlock switches are located on the nose landing gear downlock brace or main landing gear side brace actuator. The uplock switches are located on the nose landing gear fairing door frame and main landing gear fairing door frame.
Is one of the most common problems encountered while inspecting wheels?
Corrosion is one of the most common problems encountered while inspecting wheels. Locations where moisture is trapped should be checked closely. It is possible to dress out some corrosion according to the manufacturer’s instructions.
What is the most critical area on a wheel?
wheel bead seat
To ensure safe aircraft takeoffs and landings, one of the most vital areas to inspect for possible fatigue cracking and heat damage is the wheel bead seat, the critical area where the rubber edge of a tire contacts the wheel.
What is inboard and outboard in aircraft?
Adj. 1. inboard – located within the hull or nearest the midline of a vessel or aircraft; “the inboard flaps on the wing” outboard – located away from the midline of a vessel or aircraft; “the outboard section of a wing”; “outboard rigging”
What kind of brakes do airplanes use?
The most common type of brake used on aircraft is the disc brake. Disc brakes function by exploiting friction between rotating and stationary discs inside the brake.
What is Uplock landing gear?
Tactair Landing Gear/Door Uplocks utilize a simple and robust mechanical latching design for retaining the Landing Gear in the ‘Up’ position. The latching design includes two methods of release for lowering the landing gear, a normal and alternate mode.
What is a squat switch?
Squat Switch. An electrical switch mounted on one of the landing gear struts. It is used to sense when the weight of the aircraft is on the wheels.
What are the visible signs of excessive heating on a wheel bearing?
What are the visible signs of excessive heating on a wheel bearing? The bearing surfaces show discoloration. How are the pilot’s nose wheel steering commands transmitted to the steering control unit of a large aircraft? Steering signals may be transmitted mechanically, electrically, or hydraulically.
