Provided Services

King Air Phase Inspections

The most common maintenance for King Air operators is the Phase inspection cycle—Phase 1 through 4. These occur every 200 flight hours, with all four required within 24 months. Many operators choose to combine inspections to reduce downtime, especially if flying fewer than 400 hours in two years.

A typical Phase inspection covers critical areas such as:

Landing gear and retraction systems
Engines
Cabin section
Wings
Operational components
Rear fuselage

King Air Detail Inspections

For newer, Pro Line Fusion–equipped King Airs, inspections follow a Detail inspection program instead of Phase inspections. Although the types of items reviewed during a Detail inspection are similar to the items that get reviewed in a Phase inspection, the intervals are different. There are four—Detail 1 through 4—each due every 200 hours. If fewer than 200 hours are flown in 24 months, a dual inspection is required. All four must be completed within 48 months.

Five-Year Wing Bolt Inspection

Every five years, a King Air wing bolt inspection is required. This includes visual and fluorescent liquid penetrant of the Inconel wing bolts and nuts. It also includes a magnified visual and eddy current as specified left and right outboard wing lower forward main spar fittings. Eddy current is also used to inspect flat surfaces, depressions, counterbores, and bolt bores at the upper forward, upper and lower aft wing attach points.

Engine Minor Inspection

An engine minor inspection is typically done in conjunction with a phase inspection and is due every 400 hours. This inspection includes:

Replacement of fuel pump outlet filter
Check and cleaning of the fuel pump inlet screen
Cleaning of P3 filter drain
Inspecting of the engine control linkages
Check oil filter element and secondary screen

72-Month/2,500 Cycle Cockpit and Cabin Interior Inspection

The King Air 72-month/2,500 cycle cockpit and cabin interior inspection require the interior of the aircraft to be removed. The inspection includes:

Visual inspection of the cockpit and cabin fuselage skins and structures
Visual inspection of the environmental ducting
Visual inspection of the electrical wiring
Visual inspection of the plumbing
Visual inspection of the oxygen system, components, and plumbing for damage and security of attachment

Altimeter and Pitot Static System Check

This maintenance item checks the entire pitot-static system to include:

Leak check in the pilot and copilot pitot-static system
Tests on the ATC transponder
Test of EFIS display
Inspection of the air data system
Test of the air data computer

De-ice boot replacement

De-ice boots need regular maintenance including cleaning and proper care techniques. As the de-ice boots age, they have the tendency to crack and weather to the point where they need replacement. When a de-ice boot needs replaced, there are PMA and factory parts options.

Right and Left Engine Flammable Fluid Hose Replacement

Each engine contains 15 flammable fluid hoses. These hoses transfer all of the flammable fluids throughout the engine compartments. Hose replacements are required to be changed every five years.

Brake Hose Replacement

The exposed brake hoses in the wheel well of the main landing gear transfer hydraulic fluid to the baking system. The brake hoses are required to be replaced every five years.

Gear Extend/Retract Hose Replacement

The exposed extend/retraction hoses of the nose and main landing gear enable the landing gear to extend and retract. They are required to be replaced every ten years.
