- 2 - the aircraft engines the flight engineer used the electrically driven auxiliary hydraulic pump to build the hydraulic pressure to 3000 p.s.i. in the accumulators. The emergency hydraulic pump elector valve lever was then placed in the normal forward (brakes only) position. The engineer said that he did not move the by-pass lever, and that in accordance with the checklist, it was in the down position. While performing other associated duties the flight engineer noted in the log that hydraulic work had been done on the aircraft.

When the captain and the first officer boarded the aircraft the flight engineer advised the captain that the checklist had been completed. The captain then set the parking brakes.

Shortly before the engines were started a Delta mechanic entered the flight deck and explained to the captain the modification that had been made in disconnecting the Meletron switch and capping the hydraulic line to the switch. He also explained that disconnecting this unit in no way affected the normal operation of the hydraulic system. The mechanic stated that the captain, at his request, operated the auxiliary hydraulic pump; and both men were satisfied that the pump operated.

After performing their assigned functions in the cabin the stewardesses both went forward to the cockpit to observe the takeoff from the flight deck. One occupied the observer's seat directly behind the flight engineer and the other seated herself in a jump seat near the crew entrance door.
