Nav Aids LTD APA85390L-4-4-4-4 - Pitot Static Test Adaptor

The Nav-Aids APA85390L-4-4-4-4 - Pitot Static Test Adaptor is a left-hand aircraft-specific pitot static test adaptor designed for the Embraer KC-390. This adaptor is used to connect compatible air data test equipment to the aircraft pitot and static sensing system for source testing, leak checks, troubleshooting, and maintenance verification. Built for precise fit and dependable sealing, it is intended for maintenance teams that need repeatable test setup and reliable pneumatic connection during air data system servicing on this military transport platform.

Because the KC-390 operates in demanding tactical, transport, and multi-role environments, accurate pitot static testing is critical for flight instrument reliability, air data performance, and safe return to service after inspections or repairs. The APA85390L-4-4-4-4 supports those maintenance requirements by giving technicians an adaptor engineered for quick installation, leak-free operation, and proper accommodation of combined pitot and static sensing functions where required by the aircraft probe design.

Key Features

• Aircraft-specific pitot static test adaptor for the Embraer KC-390.
• Left-hand adaptor configuration for the applicable aircraft probe location.
• Designed for pitot static system testing, air data troubleshooting, and leak checks.
• Supports direct connection of compatible air data test equipment to the aircraft source.
• Engineered for repeatable installation and dependable sealing during maintenance procedures.
• Suitable for military aviation, government fleet support, depot maintenance, and contractor logistics environments.

Design and Testing Function

This pitot static test adaptor is built to provide a controlled pneumatic interface between the aircraft sensing probe and the air data test set. Nav-Aids adaptors are designed for easy installation and leak-free operation, with internal seals and spacers that support a secure connection without metal-to-metal contact at the probe interface. Where the aircraft pitot tube also incorporates static sensing, the adaptor is configured to accommodate testing of both systems through the same installed unit.

Applications

The APA85390L-4-4-4-4 is well suited for military airlift operators, defense maintenance organizations, special mission support providers, and aerospace test teams maintaining Embraer KC-390 aircraft. It is particularly useful during scheduled inspections, avionics troubleshooting, pitot static certification work, and post-maintenance air data verification where aircraft-specific pitot static adapters are essential for accurate results.
