Narrative:

We missed the engine ignition switch on the after landing checklist. Unlike all of our other MD80's, those that I've flown here for 12 yrs (at least some we bought from another air carrier) have an ignition system that does not have a continuous ignition option. They have an ignition switch which is off or in 1 of 2 high joule position. Our checklist has been modified so that, on these aircraft, the ignition is turned on shortly before landing and turned off during the after landing checklist. On the other MD80's, the ignition is placed in during the descent checklist and turned off during the parking checklist. This was the second leg we had flown on a newly acquired aircraft. After landing, we had to wait quite a while to pull into the gate because the ramp was closed, due to lightning in the area. During the parking checklist, I realized that the ignition was still on and that it's duty cycle had been exceeded. I wrote it up in the logbook. Frankly, the only reason that we didn't forget to turn it off after landing during the first leg, was because we forgot to turn it on. During descent I reached up to turn it on and realized that it was too early, but then we didn't get it on before landing. While discussing this later, the first officer brought up what seems to be a reasonable suggestion. If we standardized turning off the ignition during the after landing checklist, we could save igniters on the new aircraft, yet not hurt anything on the old aircraft. We have, in fact, changed the after takeoff checklist, standardizing turning the ignition off during the cleanup rather than waiting for 10000 ft as we formerly did.

Title: AN MD80 CAPT RPTED PROBS REMEMBERING TO TURN ON-OFF THE ENG IGNITION SWITCH IN 2 DIFFERENT COCKPIT LAYOUTS OF THE SAME ACFT.

Narrative: WE MISSED THE ENG IGNITION SWITCH ON THE AFTER LNDG CHKLIST. UNLIKE ALL OF OUR OTHER MD80'S, THOSE THAT I'VE FLOWN HERE FOR 12 YRS (AT LEAST SOME WE BOUGHT FROM ANOTHER ACR) HAVE AN IGNITION SYS THAT DOES NOT HAVE A CONTINUOUS IGNITION OPTION. THEY HAVE AN IGNITION SWITCH WHICH IS OFF OR IN 1 OF 2 HIGH JOULE POS. OUR CHKLIST HAS BEEN MODIFIED SO THAT, ON THESE ACFT, THE IGNITION IS TURNED ON SHORTLY BEFORE LNDG AND TURNED OFF DURING THE AFTER LNDG CHKLIST. ON THE OTHER MD80'S, THE IGNITION IS PLACED IN DURING THE DSCNT CHKLIST AND TURNED OFF DURING THE PARKING CHKLIST. THIS WAS THE SECOND LEG WE HAD FLOWN ON A NEWLY ACQUIRED ACFT. AFTER LNDG, WE HAD TO WAIT QUITE A WHILE TO PULL INTO THE GATE BECAUSE THE RAMP WAS CLOSED, DUE TO LIGHTNING IN THE AREA. DURING THE PARKING CHKLIST, I REALIZED THAT THE IGNITION WAS STILL ON AND THAT IT'S DUTY CYCLE HAD BEEN EXCEEDED. I WROTE IT UP IN THE LOGBOOK. FRANKLY, THE ONLY REASON THAT WE DIDN'T FORGET TO TURN IT OFF AFTER LNDG DURING THE FIRST LEG, WAS BECAUSE WE FORGOT TO TURN IT ON. DURING DSCNT I REACHED UP TO TURN IT ON AND REALIZED THAT IT WAS TOO EARLY, BUT THEN WE DIDN'T GET IT ON BEFORE LNDG. WHILE DISCUSSING THIS LATER, THE FO BROUGHT UP WHAT SEEMS TO BE A REASONABLE SUGGESTION. IF WE STANDARDIZED TURNING OFF THE IGNITION DURING THE AFTER LNDG CHKLIST, WE COULD SAVE IGNITERS ON THE NEW ACFT, YET NOT HURT ANYTHING ON THE OLD ACFT. WE HAVE, IN FACT, CHANGED THE AFTER TKOF CHKLIST, STANDARDIZING TURNING THE IGNITION OFF DURING THE CLEANUP RATHER THAN WAITING FOR 10000 FT AS WE FORMERLY DID.
