Narrative:

During takeoff roll at stl, I noticed that the right thrust reverser accumulator low light had come on, on the over head annunciator panel. Our speed was near 100 KTS and because thrust reversers are deferrable, I decided not to abort the takeoff. Company policy precludes aborts for anything that does not imminently affect the safety of flight. On landing at lga, the right thrust reverser did not deploy. The landing was normal with no difficulty stopping. Maintenance discovered the right thrust reverser had been shut off externally. This would not normally be noticed during walk around inspection because this shutoff is located behind a closed access cover and is a maintenance function. I did not notice the reverser accumulator low light being on during taxi at stl, so I assumed that it had come on during takeoff, but in reflecting, it may be that I had missed the light on the annunciator panel because of single engine taxi which causes many lights to be illuminated during taxi. The MD83 has a scroll type annunciator panel, and lights move around continually. I may have become complacent expecting to see lights on during taxi. Because these lights are on the overhead and my bifocals blur anything in that area unless I make a conscious effort to tilt my head back. From now on, I will make a conscious effort to read every light on this panel before each takeoff. Supplemental information from acn 316198: next day we found out that the aircraft had been in the hangar for maintenance. The mechanics had left the right reverser lockout pin in place.

Title: THRUST REVERSER LOW PRESSURE ACCUMULATOR WARNING LIGHT ILLUMINATES DURING TKOF.

Narrative: DURING TKOF ROLL AT STL, I NOTICED THAT THE R THRUST REVERSER ACCUMULATOR LOW LIGHT HAD COME ON, ON THE OVER HEAD ANNUNCIATOR PANEL. OUR SPD WAS NEAR 100 KTS AND BECAUSE THRUST REVERSERS ARE DEFERRABLE, I DECIDED NOT TO ABORT THE TKOF. COMPANY POLICY PRECLUDES ABORTS FOR ANYTHING THAT DOES NOT IMMINENTLY AFFECT THE SAFETY OF FLT. ON LNDG AT LGA, THE R THRUST REVERSER DID NOT DEPLOY. THE LNDG WAS NORMAL WITH NO DIFFICULTY STOPPING. MAINT DISCOVERED THE R THRUST REVERSER HAD BEEN SHUT OFF EXTERNALLY. THIS WOULD NOT NORMALLY BE NOTICED DURING WALK AROUND INSPECTION BECAUSE THIS SHUTOFF IS LOCATED BEHIND A CLOSED ACCESS COVER AND IS A MAINT FUNCTION. I DID NOT NOTICE THE REVERSER ACCUMULATOR LOW LIGHT BEING ON DURING TAXI AT STL, SO I ASSUMED THAT IT HAD COME ON DURING TKOF, BUT IN REFLECTING, IT MAY BE THAT I HAD MISSED THE LIGHT ON THE ANNUNCIATOR PANEL BECAUSE OF SINGLE ENG TAXI WHICH CAUSES MANY LIGHTS TO BE ILLUMINATED DURING TAXI. THE MD83 HAS A SCROLL TYPE ANNUNCIATOR PANEL, AND LIGHTS MOVE AROUND CONTINUALLY. I MAY HAVE BECOME COMPLACENT EXPECTING TO SEE LIGHTS ON DURING TAXI. BECAUSE THESE LIGHTS ARE ON THE OVERHEAD AND MY BIFOCALS BLUR ANYTHING IN THAT AREA UNLESS I MAKE A CONSCIOUS EFFORT TO TILT MY HEAD BACK. FROM NOW ON, I WILL MAKE A CONSCIOUS EFFORT TO READ EVERY LIGHT ON THIS PANEL BEFORE EACH TKOF. SUPPLEMENTAL INFO FROM ACN 316198: NEXT DAY WE FOUND OUT THAT THE ACFT HAD BEEN IN THE HANGAR FOR MAINT. THE MECHS HAD LEFT THE R REVERSER LOCKOUT PIN IN PLACE.
