PM51 - PM Research FAA-PMA Radome Boot

PM51 – PM Research FAA-PMA Radome Boot

Available now on the Airparts.aero Marketplace.

Overview

The PM Research PM51 is an FAA-PMA approved radome boot, engineered as a high-quality, direct replacement for the original B.F. Goodrich P/N 50-1416-1. This boot is a critical aerodynamic and protective component for the nose-mounted weather radar radome on a wide range of Beechcraft King Air aircraft. Fabricated from a durable, erosion-resistant elastomer, the PM51 is designed to protect the leading edge of the radome from damage while creating a smooth, aerodynamic seal between the radome and the aircraft's fuselage.

Key Features

• Superior Erosion Protection: Its primary function is to act as a sacrificial shield, protecting the fiberglass radome from erosion caused by rain, hail, ice, and airborne particulates at high speed. This prevents damage to the structurally and electronically sensitive radome.
• Aerodynamic Sealing: The boot is designed to provide a smooth, continuous fairing between the radome and the nose of the aircraft. This reduces parasitic drag and minimizes air and moisture intrusion into the radome-fuselage gap.
• Durable Elastomeric Construction: Manufactured from a high-grade, flexible polymer compound. This material is chosen for its excellent resistance to UV radiation, ozone, temperature extremes, and common aviation fluids, ensuring a long service life.
• Direct PMA Replacement: A certified FAA-PMA direct replacement for B.F. Goodrich P/N 50-1416-1, guaranteeing perfect form, fit, and function while providing a cost-effective alternative to the original OEM part.
• Maintains Radar Performance: By protecting the radome surface from erosion and delamination, the boot helps to maintain the radome's specific dielectric properties, which are essential for the proper transmission and reception of weather radar signals.

  • Beechcraft King Air: 200, B200 (Super King Air)

Applications

The PM51 is an essential component for maintaining the airframe and avionics systems:

• Radome Protection: The primary defense against damage to the expensive radome assembly.
• Scheduled Maintenance: A common replacement item during major inspections or any time the old boot is found to be cracked, crazed, or excessively eroded.
• Aerodynamic Performance: Helps to maintain the clean aerodynamic lines of the aircraft's nose section, reducing drag and noise.

Why Choose PM51?

A damaged or eroded radome can allow moisture to penetrate its composite layers, which can significantly degrade the performance of the weather radar system inside. The PM Research PM51 boot is a robust, FAA-PMA approved solution that protects this critical and high-value component. As a leader in PMA components, PM Research provides a part that meets or exceeds the performance of the original, ensuring the safety, value, and aerodynamic efficiency of your aircraft.

The PM51 radome boot plays a crucial role in maintaining the integrity of the weather radar system. A radome is not just a simple fiberglass fairing; it is an electronically transparent window for microwave energy. Its shape and material thickness are precisely controlled to minimize signal attenuation and distortion (boresight error). Rain erosion can pit the surface of the radome, causing water to collect in the divots. This layer of water can significantly reflect and absorb the radar's energy, dramatically reducing its ability to detect distant weather cells. The PM51 boot provides a smooth, renewable, hydrophobic surface that protects the radome's delicate structure and ensures the radar can perform at its certified capability.

Note: This is an airframe component. Installation requires the removal of the radome from the aircraft. The boot is typically installed with a specialized adhesive. This task must be performed by a certified A&P mechanic or at a qualified repair station in accordance with the aircraft's maintenance manual.
