Narrative:

We had no passenger on board for our flight back to dtw. Captain and I had been flying together for 2 days. As we finished the before takeoff checklist, he let me (the first officer) taxi the airplane onto the runway for takeoff (even though this was my leg to fly, this isn't company policy to let the first officer taxi for takeoff). As such, I neglected to rechk our final items because I was trying to taxi the aircraft. The captain, unfamiliar with my duties, pulled out the checklist to ensure nothing was missed. Unfortunately, he neglected (or I neglected, since it was actually my responsibility) to make sure the propeller levers were pushed all the way to high for takeoff. As I added power, the left engine began to surge and the 'blue bypass' light came on for the left engine. We aborted the takeoff. After running the engine up on the taxiway, we discovered the problem. We then taxied out for departure with an uneventful takeoff and climb.. This time doing our own jobs as trained by the company. Lesson learned: don't switch duties, especially during critical phases of flight, it could be disastrous. Fortunately for us, nothing was hurt, except our pride.

Title: TKOF ABORTED BY LTT CREW.

Narrative: WE HAD NO PAX ON BOARD FOR OUR FLT BACK TO DTW. CAPT AND I HAD BEEN FLYING TOGETHER FOR 2 DAYS. AS WE FINISHED THE BEFORE TKOF CHKLIST, HE LET ME (THE FO) TAXI THE AIRPLANE ONTO THE RWY FOR TKOF (EVEN THOUGH THIS WAS MY LEG TO FLY, THIS ISN'T COMPANY POLICY TO LET THE FO TAXI FOR TKOF). AS SUCH, I NEGLECTED TO RECHK OUR FINAL ITEMS BECAUSE I WAS TRYING TO TAXI THE ACFT. THE CAPT, UNFAMILIAR WITH MY DUTIES, PULLED OUT THE CHKLIST TO ENSURE NOTHING WAS MISSED. UNFORTUNATELY, HE NEGLECTED (OR I NEGLECTED, SINCE IT WAS ACTUALLY MY RESPONSIBILITY) TO MAKE SURE THE PROP LEVERS WERE PUSHED ALL THE WAY TO HIGH FOR TKOF. AS I ADDED PWR, THE L ENG BEGAN TO SURGE AND THE 'BLUE BYPASS' LIGHT CAME ON FOR THE L ENG. WE ABORTED THE TKOF. AFTER RUNNING THE ENG UP ON THE TXWY, WE DISCOVERED THE PROB. WE THEN TAXIED OUT FOR DEP WITH AN UNEVENTFUL TKOF AND CLB.. THIS TIME DOING OUR OWN JOBS AS TRAINED BY THE COMPANY. LESSON LEARNED: DON'T SWITCH DUTIES, ESPECIALLY DURING CRITICAL PHASES OF FLT, IT COULD BE DISASTROUS. FORTUNATELY FOR US, NOTHING WAS HURT, EXCEPT OUR PRIDE.
