Embraer just released revision 25 of the Phenom 300 AFM, it contains an updated procedure for ECS 1/2 VALVE FAIL that allows one FCSOV reset. Note that that the QRH have yet to be updated, but I assume that is around the corner.



A new FOL PHE505-002/2023 was also released, CRITICAL FUEL SCENARIOS FOR THE NEW EASA FUEL/ENERGY RULES. To comply with these new requirements, Embraer is providing tables for each airplane in these two critical fuel scenarios.

For depressurization:

- Emergency descent from cruise flight level to 10000 ft,
- Long Range Cruise at 10000 ft,
- Descent at the standard AOM descent speed to 1500 ft AGL,
- 15 minutes holding at 1500 ft AGL, and
- Approach and landing.

For engine failure:

- Driftdown maneuver at AOM recommended driftdown speed,
- Long Range Cruise at cruise altitude capability with one engine inoperative (remaining rate of climb 100 ft/min and buffet margin 1.3 g),
- Descent at the standard AOM descent speed to 1500 ft AGL,
- 15 minutes holding at 1500 ft AGL, and
- Approach and landing.

As expected, the matching Phenom 300 QRH r24 (JUNE 06, 2023) was just released on techpubs.

Thanks for the heads up. Just updated FOL, QRH, OB, and AFM which all have revisions March ‘23 onward. Happy flying.

Quick question. I’m new to the p300, had the ECS-1 failure climbing through FL320 today. Attempted the reset, but, did not work. How often does it allow a reset?

We ended up with a new valve…. 70 cycles since the fix and no issues.
