Numbers On Landing Gear Door

Sun Jun 24, 2001 6:01 am

I was spotting at DEN and couldn't get a clear read on a United 737 Reg. Number. But on the front gear door there was the number 1303. Does anyone know what this stands for? Thanks!

The numbers u see on the nose-gear doors are the shipping number of the plane delivered to the airlines from the manufacturers.

Shipping Number? HAHAHAHAHAHA WRONG. Each airline has their own method of numbering their fleet. UA can get complicated. In this case of 1303 it is most likely 737-322 N303UA.

The number/letter (if your not in the US) is the plane's ship number. THe airline assigns a number to each plane. For example, N303DL is a Delta 737-232. The registration is on the fuselage, but on the tip of the tail and on the landing gear door is the number 303. G-VIIC (BA 777-236) has IC on its landing gear door and tail tip. Some airlines have them in different places (ie the new DL, BA colours don't have the numbers at the tip) but have them on the door. The number gives the airline another way of easy identification (the number is also used on logbooks, etc.)

US carriers use fleet numbers on the nosegear door, which generally bear no relationship to the registration number.

European airlines, and most of the rest of the world, generally place the last 2 letters of the registration on the nosegear door.

Many airlines also place a small "ETOPS" designation on the nosegear doors of aircraft that are certified to operate such flights.

Air Canada has fin numbers for their aircraft. Each type of aircraft has a range.
747 combi's are 341,42,43 ex-CP 381,82,84,85
320's- 201-232 ex-CP 401-416
319's- 251-28? 737's 500 series
DC-9's- 700 series F-28's- 100 BAE-146's-200 series
767's-600 series Dash8's 800/300 series.
A-340's-901-910&981/82 A-330's-931-936

One of these numbers will appear on the tail and front gear doors of AC aircraft with the registration on the fuselage.

The number is the UA fleet number and the aircraft you saw was B737-300 N303UA. Another version of the fln is 9303 (this is what they put in jp at least)

Even easier yet from Air Canada, take a look at their fleet site. A welcome addition to any airline website - at least someone at Air Canada seemed to realize that the flying public and spotters alike would be interested in the a/c type they see based on the tail number. Can't say that much about other airlines around the world.
