On Dec 29th 2012 it became known after another TU-204 overran the runway at Moscow Vnukovo, see Accident: Red Wings T204 at Moscow on Dec 29th 2012, overran runway on landing, that on Dec 28th Rosaviatsia had alerted the aircraft manufacturer Tupolev of a brakes malfunction as cause of the overrun at Novosibirsk. In a letter dated Dec 24th 2012 Rosaviatsia demanded with reference to this overrun that all operators of Tupolev TU-204 should perform an extra lubrication to grease the drive mechanism limit switches that are crimped onto the main landing shock absorber before next departure.

On Dec 31st 2012 Rosaviatsia released a modification to aircraft operations manual requiring flight crew to apply reverse thrust only if the engine is operating (stating application of reverse thrust is prohibited on a malfunctioning engine). To apply reverse thrust the engine should be pulled to idle for 1-2 seconds, then command reverse thrust at minimum thrust, verify yellow "thrust reverser unlocked" followed by green "REV" indications appear, only then apply high reverse thrust. Rosaviatsia reported there have been a number of cases where the green "REV" indication did not appear (editorial note: there have been rumours since this overrun, that the crew had applied reverse thrust, the reverser however had not opened and at least one of the engine was delivering full forward thrust instead).

Capt Inop - are you going to 'revise' your post about reversers+g/a ie "when you go balls to the walls for a GA." or does your airline have different operating restrictions to Boeing and AB?

going around after selction of Reverse is prohibited

---

---

engines on idle reverse will produce usefull forward thrust faster than if they are spooled up in reverse

Quickly stowing them from full reverse will give you a jolt up the

the possibility of a reverser door not stowing during your aforementioned fire-walling for a G/A

(2) The engine control throttle levers are located on middle isle. Automatic operation of the engine is the controlled by thrust control unit VSUT-85 (Thrust Control Computer).
To avoid the possibility of a kickback there is the throttle brake.
When VSUT is switched ON with throttles blocked on IM#2 displayed "UNBLOCK THROTTLE".
On the throttle lever there is inbuilt devices which disable VSUT by applying 1.5 - 2 kg force to the handle.
Buttons are located on the throttle manually activate high thrust (PR), see Fig. 8.1.10.
Modes of operation of the engine and the corresponding throttle position are shown in Table 8.1.1.

8.1.1.2 The system of reverse thrust

(1) Reverse device and its control units mounted on the engine and are designed for reverse thrust.
Return (negative) thrust is created by changing the air flow direction
by opening or closig the flaps of reversing device. Flaps can be set
in one of two positions: DIRECT THRUST or BACK THRUST.
Shifting of the flaps is made by hydraulic cylinders, which pistons
are connected to the control lever mechanism.
...
(2) The thrust reverser controlled by pilots with Reverse Control Levers (RCL)mounted on the Throttle Levers (TL).
Before turning on the reverser, throttle is moved to IDLE, RCL in the lower
(Off) position is fixed by latch. The reverse thrust value is determined by the RCL up position similarly to TL position when managing direct thrust.
To enable small reverse thrust RCL must be removed from the latch by pressing the RCL lever head down and move lever to the intermediate stop (small reverse).
To enable maximum reverse bring RCL all the way to the "maximum reverse" stop.
(3) Reverse control light signal device is located on the Pilots instrument panel:
- REVERSE LOCK is yellow;
- REVERSE ON is green.
In addition, information on operation is on the IM#2, in the frame
ENG / SIGN (ENG MAIN, ENG GEN):
- When reverse lock is open - LOCK (yellow);
- When the reverse is ON - REV (green).
