IntroductionOK so you have seen the EQUIP caption & know roughly where the hatch is, but you are still curious to see what is inside. If you are going to attempt a peek in here away from this site then I recommend that you get an engineer to show you how to open, and more importantly, close the hatch, it is not straightforward. There are actually 2 hatches which trigger the EQUIP light. The electronic equipment compartment located aft of the nose wheel well and the forward equipment compartment located forward of the nose wheel well. Most of the equipment is in the electronic equipment compartment. Also in the electronic equip compartment is the forward airstair door mechanism. The jackscrew is for the extension and retraction of the airstairs. The normal and standby motors are in the green housings at the base of the jackscrew.

The battery is also located in the E&E bay. On the Classics it sits on the external DC power receptacle which is used to start the APU if the battery voltage is insufficient. Note this is not fitted to the NG/MAX because if the battery voltage is that low it must be replaced. Click on the photos to enlarge and find out what lurks behind
this hatch.
For a location chart of all of the E & E bay components see the book. Fluid IngressOn 22 October 1995, G-BGJI, a 737-200Adv experienced undemanded yaw & roll oscillations during an air test. This was put down to fluid from the cabin leaking into the E & E bay and onto the yaw damper coupler. The report stated:
Only the E1 rack is vulnerable to fluid ingress because it is directly below the forward entry door, the other racks are much further aft. For protection the classics have a carpet over the E1 rack and the NG's have drip trays over all racks. The time to be careful is when the forward doors are open on a turnaround with heavy rain coming in. |
