Adhere strictly to the cooling periods between start attempts to prevent overheating the starter-generator windings.
Maintenance manuals for ATR aircraft undergo continuous revisions to reflect Airworthiness Directives (ADs), Service Bulletins (SBs), and fleet performance data. Why the Manual Date Matters
(officially the 72-212A) is a short-haul twin turboprop with a Maximum Take-Off Weight (MTOW) of 23,000 kg and a range of approximately 1,500 km. It features a fully integrated digital cockpit and an electronic standby instrument (IESI). When looking for the official document ( atr

Operational safety instructions in Chapter 80 are vital to prevent catastrophic component failure or personnel injury. Importance of the 2021 Manual Revision Electrical Power
Unlike larger commercial jets that use pneumatic (air) starters, the ATR 72-600 utilizes an electrical starter-generator mounted on the accessory gearbox of each engine. During the start cycle, it acts as a DC motor. Once the engine runs autonomously, it switches to function as a 28V DC generator.

The ATR 72-600 AMM Chapter 80 governs the safe execution of engine starting routines, component overhauls, and preventative maintenance. Adhering strictly to the 2021 revised torque limits, brush wear tolerances, and multi-function computer logic tests ensures fleet safety and reduces unplanned maintenance delays.
Because engine starting involves high-voltage electricity, high-speed rotational components, and flammable aviation fuel, Chapter 80 contains strict warnings:
An electrically controlled, pneumatically operated butterfly valve that regulates the flow of bleed air to the starter.
