What is the significance of a proper static wick inspection during an annual?
Answer: Damaged or missing static wicks can cause static interference with navigation and communication radios
Static wicks dissipate precipitation static charge; missing or damaged wicks allow charge buildup that causes significant radio interference, affecting navigation and communication.
When inspecting a digital glass cockpit (EFIS) installation during an annual, what is the IA primarily concerned about?
Answer: Proper installation per the approved data, secure mounting, correct wiring, and functional backup systems
Glass cockpit inspections focus on installation compliance with the approved STC or type design, structural security, wiring integrity, and verification that required backup instruments are installed and functional.
An IA inspects a fuel quantity indicating system and finds it reads 5 gallons low when compared to a measured fill. What must happen before return to service?
Answer: The inaccuracy must be documented and corrected or the inaccuracy noted on a placard if it can be deferred per applicable rules
Fuel quantity inaccuracies are an airworthiness concern; the IA must either correct the system or ensure the inaccuracy is properly documented and placarded if deferrable.
What does an IA check about the aircraft's audio panel and intercom system during an annual inspection?
Answer: Secure mounting, proper wiring, freedom from interference, and that all switching functions operate correctly
Audio system inspection during an annual covers physical security, wiring condition, and functional verification of all switching and audio paths.
What must an IA verify about an aircraft's ADS-B Out system during an annual inspection?
Answer: That if ADS-B Out is installed, it is functioning per the approved installation and meets performance standards for the airspace in which it is used
ADS-B Out required in certain airspace under 14 CFR 91.225; the IA must verify that installed systems comply with 14 CFR 91.227 performance requirements and are properly installed.
