A Little Gem from CASA Experts
Folks,
From a new AWB:
AIRWORTHINESS BULLETIN
AWB 85-023 Issue 1 – 3 April 2018
Piston Engine Spark Plug Insulator Cracking
Fuel Management - Lean-of-peak operation where precise control over the engine's performance cannot be assured is to be avoided to negate the possibility of detonation. For appropriate fuel leaning practices refer to the aircraft POH (pilot's operating handbook) or AFM (aircraft flight manual), as applicable, for specific instructions.
And we are supposed to take CASA seriously???
Tootle pip!!
