PWI’s Lighting Refit PMA Now Covers All Beechjets

Wichita-based aircraft lighting specialist PWI has received FAA parts manufacturer approval for its LED cabin lighting system for the Beechjet 400A/Hawker 400XP light jets. This latest authorization follows one announced earlier this year for the type and covers the remainder of the 400-series Beechjets, including the widest serial number range and the largest number of registrations.

The PWI system is a replacement for aging fluorescent lights and uses the same wiring and aircraft-supplied voltage. Through the use of LEDs, it eliminates fluorescent-related problems such as light flicker, background hums or buzzing, and ongoing maintenance. The removal of high-voltage fluorescent power supplies also eradicates potential electrical interference in the aircraft.

PWI cabin LED lighting systems—available directly from the manufacturer or its authorized dealer network—are 4,000K neutral white, offer 100,000-hour service life, and create no heat. The replacement LEDs match the original fluorescent tube lengths and carry a three-year warranty. The system requires installation by a qualified repair station; therefore, PWI recommends scheduling the installation during a maintenance event to minimize downtime.

“Our goal was to leverage our five decades of aircraft lighting experience and bring the 400-series Beechjet cabin experience up to today’s standard,” said PWI president Robi Lorik.
