The Federal Aviation Administration (FAA) has released a proposed rule to establish a new airworthiness directive (AD) for several models of Rolls-Royce turbofan engines. This proposed directive is a response to changes made by the manufacturer to the time limits manual (TLM), which now includes repairs for low-pressure compressor (LPC) blades and new fan blade inspections. The goal is to prevent potential engine failure caused by critical rotating parts, which could lead to loss of thrust and control of the aircraft. Stakeholders are invited to comment on the proposal by April 9, 2021.
Simple Explanation
The FAA wants to make sure certain airplane engines stay safe, so they are telling the people who take care of these engines to do some new checks and fixes on them. This is like when a teacher reminds the class to check their homework to make sure everything is done right and nothing is missed.
