Early Cessna 150 Inspection, Tips, Tricks, and Hints


"Everything you always wanted to ask about the 1959-1963 Cessna 150's but were afraid (or didn't know) to ask."

Well...... not quite everything, but a lot of info and photos.

And a Bunch of Stuff that Later 150 and 152 Owners can find Useful Too!

Miscellaneous Items and Quirks of the Early 150's  

Aviation Links (FAA, FAR's, AD's, NPRM's, aircraft manufacturers, type clubs, parts suppliers, etc)


Here are two articles by FAA inspector Bill O'Brien related to owner performed maintenance and owner produced parts. Follow the links below to see them and use your browsers back button to return to this page. Good information for the non-A&P aircraft owner.

O'Brien on owner performed preventative maintenance

O'Brien on owner produced/manufactured parts

Another article on owner produced parts, this one by Don Dodge, of the South Carolina FSDO as published in FAAviation News, July/August 2002 edition.

While the intent of this web site is the early 150 models, much of the information is applicable to later aircraft, so don't go away if yours is not an early model, you probably will find lots of useful information here.

First, some year/model/serial number info.
1959 150 (no letter) 17001 to 17683
1960 150 (no letter) 17684 to 17999 and 59001 to 59018
1961 150A 15059019 to 15059350
1962 150B 15059019 to 15059350
1963 150C 15059701 to 15060087
1964 150D 15060088 to 15060772 also 644
1965 150E 15060773 to 15061532

One thing which everyone will find confusing is Cessna's numbering and naming system for bulletins. At one time the numbering system was a model, such as 150, followed by a hyphen and another number which is a sequence number. This became a problem as information many times affected more than one model of aircraft and searching 150 bulletins does not turn up all information pertaining to 150's, one must go look in 175, 172 and such bulletins. Cessna later came out with a new numbering system using the year, ie. 65 followed by a hyphen and a sequence number. Cessna also called its letters Service News Letters for a while, then just plain Service Letters. More recently they have called the letters SE and ME for single engine and multi-engine, except that the Skymasters are included in the Single Engine catagory.  Confusing to say the least.

If you are interested in learning more about your Cessna 150 or 152, as an owner or pilot, from a mechanical or operational standpoint, there are a couple of different discussion groups on the web you should consider participating in.

The Cessna 150-152 Club has a forum which you can join, which is divided into different topics of discussion such as Technical matters, Piloting, the Club's 2004 national fly in at Clinton, Iowa, and a Everything else category. The forum runs on the very user friendly UBBThreads software and I highly encourage you to participate. Go to to register.

The Cessna 150_152  discussion group (no longer related to the Club), is found on Yahoo Groups. You do not have to be a Cessna 150-152 Club member to participate and the official club discussion group has moved to its own server Just follow to the link below for more information, or to see what is happening, follow the link below directly to the threads. We'd love to hear from you. Click here to go to the homepage at Yahoo. It is necessary to join Yahoo Groups to participate, however this is a formality.



Some advertising for products you can use!

Some very good, long time, friends of mine, Rick and Judy Skrzypkowski have a home business. They are making name badges, bag tags, engraved plastic signs, trophies, etc. The bag tags are not some cheesy thin stuff but rather a real thick, fiberglass reinforced plastic that can withstand the roughest bag handlers. He can print your own photograph on the tag and then put your name and address, or whatever you want on the other side, they look real neat and everyone with a Cessna 150 needs a pic of their own airplane on a bag tag. They also do name badges and I think they can with a little effort overlay your name, etc., on the pic and print it on a badge, just the thing for Clinton or Oshkosh.


Please visit Twin Oaks Imaging at for their line of products, they will appreciate the business 

For Sale................

Sold the wingtips, but I've got a couple of other items I need to move, so keep checking back!



Need to move an airplane by trailer? A friend of mine sent me this pic when he took the wings off his Ercoupe and trailered it to have work done on the wings and an annual and reassembly done away from homebase.

Few trailers are wide enough for a coupe or a 150 for that matter. even flatbeds like you'ed haul the farm tractor on are too narrow. What my friend did was go to a building wrecking company that has a "junkyard" of salvaged building parts and found this "timber". Its rough cut wood, possibly a hundred years old, and is about 3 inches thick and about 12 inches wide. He nailed some 2x4 "chocks" to it and in this case slid it thru the trailer. Then they hefted the coupe onto it. I have used this same board on a flatbed that you haul a tractor on. Nailed it down and walked my 150 fuselage up onto the trailer by the nose gear and steadying the mains till we reached the board.

I have also seen this board used on top of a U-haul trailer, the one with 2 ft high metal sides and tubular rails above the sides. Same thing, they hefted the coupe into place and used another board for the nosegear.

I use the ratcheting type nylon straps to restrain stuff like this. You can get it tight and if need be, its easy to cinch up some more down the road if things settle and the straps get loose. The money spent on the straps is well worth it, no headaches and no damaged parts. One lesson I learned long ago, when you use ratchet straps or anything like that, always put the ratchet on the Right side of the truck, trailer or whatever. That way, when you stop alongside the highway to tighten them up. you will be out of the traffic while doing so. One word of caution with these ratchet straps, always close the lever down in the fully latched position, this locks the mechanism by bringing a couple of pawls on the handle behind the slide bar that catches the ratchet teeth, and if you do not, it can unlatch itself.
