Nav Aids LTD P77796HTP-4 - Pitot Static Test Adaptor

The Nav-Aids P77796HTP-4 - Pitot Static Test Adaptor is a high-temperature pitot test adaptor designed for Boeing 777 aircraft applications. Built for use in professional pitot static maintenance programs, this adaptor allows compatible air data test equipment to be connected directly to the aircraft source for pitot system testing, leak checks, troubleshooting, and return-to-service verification. The high-temperature configuration makes it especially suitable for applications where probe area heat exposure or elevated operating conditions must be considered during maintenance handling and testing.

On a long-range transport aircraft like the Boeing 777, accurate air data system performance is critical for flight deck indications, autopilot functions, and overall operational safety. A dedicated high-temperature adaptor such as the P77796HTP-4 helps technicians perform precise source testing through a secure, aircraft-specific interface while supporting the demands of airline maintenance, heavy base inspections, and specialist avionics troubleshooting.

Key Features

• Aircraft-specific high-temperature pitot test adaptor for Boeing 777 applications.
• Designed for source testing, leak checks, troubleshooting, and air data maintenance support.
• Supports connection of compatible pitot static test equipment through a dedicated aircraft interface.
• High-temperature configuration is suited to maintenance environments where elevated probe-area temperatures are a consideration.
• Useful in airline maintenance, transport-category MRO, avionics support, and aerospace test operations.
• Helps improve repeatability and confidence during professional pitot static testing procedures.

Known System Context

Nav-Aids identifies the P77796HTP-4 as the pitot test adaptor used in its Boeing 777 line kit configuration. In that setup it is paired with the Boeing 777 pitot probe reference 856LU, static adaptor 33410LH-125-4, pressurization port test adaptor 33410MC-125-4, Vacu-Grip assembly 532-4900, and pre-test probe PT17779. That context underscores its role in a complete aircraft-specific air data testing arrangement.

Applications

The P77796HTP-4 is well suited for airline operators, long-haul fleet maintenance organizations, widebody MRO providers, and aviation test specialists supporting Boeing 777 aircraft. It is particularly valuable wherever high-quality aircraft testing equipment is required for accurate pitot system maintenance and dependable air data verification.
