What to do
Pilots and operators of Cessna Model 402C airplanes should incorporate the temporary revisions into their POH and commit the emergency procedures for prolonged hydraulic pressure light illumination to memory. If the "HYD PRESS" light remains on longer than normal gear cycle time, pilots must promptly follow the specified procedures to avoid hydraulic system damage and cockpit smoke. No explicit compliance deadline is provided.
Summary
The Special Airworthiness Information Bulletin SAIB: CE-10-44 is a non-mandatory FAA information bulletin addressing hydraulic power indication issues on Cessna Model 402C airplanes. It highlights the meaning of the "HYD PRESS" light and the potential consequences if the hydraulic pressure indication is not properly addressed during flight operations.
What changed
The bulletin introduces temporary revisions to the Pilot's Operating Handbook (POH) for the Cessna 402C, including relocating procedures related to the hydraulic pressure light to a new Hydraulic System Emergency Procedures section. It adds a caution statement about the risk of hydraulic reservoir sight tube rupture if the hydraulic system remains pressurized too long and emphasizes immediate action procedures for pilots to memorize.
Why it matters
This bulletin is important for aviation professionals because it addresses a safety concern that could lead to hydraulic system damage and cockpit smoke due to prolonged hydraulic pressure after gear cycling. Operators and maintenance personnel need to understand the hydraulic pressure indication to prevent potential in-flight emergencies and ensure proper handling of the hydraulic system.
