ATA 12 – Grease Change
All
AeroShell 33MS grease is used as a lubricant in several areas of the King Air airplane. AeroShell has renamed this grease Aeroshell Grease 64. These greases meet the same military standard, MIL-G- 21164D. Operator concerns about the close similarity between the product names, AeroShell Grease 33 and AeroShell Grease 33MS, and the possibility of a wrong grease being used in the wrong application, resulted in the name change.

ATA 30 – King Air B200GT/B200CGT (250) Propeller Heat-Blade Damage
BY-122, BY-124 and after; BZ-1 and after
The King Air 250 is equipped with composite propeller blades. The propeller heat system heats the propeller blades anytime the Propeller Heat switch is in either AUTO or MANUAL position, whether in flight or on the ground. If the Propeller Heat system is left ON on the ground for just a few seconds without the engines running, severe damage to the propeller blades and boot will occur (see photo). There are CAUTION statements in the Pilot’s Operating Handbook Supplement and the Information for Continued Airworthiness for the propellers.
