Where Are The Six Pieces Of Wood In A 727?

Thu Aug 28, 2008 11:27 pm

I was reading an article about flying the 727 in the new issue of Airways and there was a mention of there being six pieces of wood in a 727. Where are the pieces of wood and what are they used for? Do other modern jetliners have any wooden parts?

I have no idea, but I'd strongly suspect there's at least some balsa-core composite somewhere in there.

Sometimes there would be plywood in the cargo bay.

Some of the older floor panels were made from two sheets of aluminum, with a balsa wood core.

The article reads:

"There is no better way to learn systems and procedures than instructing. But it's important to remember that just because you know the thread diameter and metallurgy of the four bolts that secure the engines to the fuselage, your students don't. Jokingly inquiring about the only letter that doesn't appear on a factory-stamped engineer's panel, or how many pieces of wood there are on a 727 is fine. But we've all suffered through instructors who lecture simply to hear themselves speak."

I assume that's the wood reference you were talking about, and I would like to know the answer as well. All I can picture is maybe a dowel inside of some tubing somewhere, if indeed he wasn't just joking!

If im not mistaken the part under engine number 2 where the aircraft can skid on when it over rotates is made out of wood. I think I read this somewhere that even the original B747's had these.

If I am not mistaken......I believe that there are several phenolic wood cable guides in the main gear wheel wells. These guides keep the control cables from rubbing and fraying on other metal structures.

While not on the 727, many years back, I was around a 707-321 that was being broken up in ACY and I found it interesting that on this particular a/c, the entire ventral fin on the aft belly fuselage was mostly made of wood...

There was a wooden piece that was used to lock the handle of rear cabin door (from the inside) to the rear stairs. This was used so that it was difficult to enter a parked/out of service/overnighting B727 aircraft (you couldn't simply walk up the stairs and go in) from the ground without using a lift truck or other vehicle to access the main doors.

Nope sorry. It was definately metal.

On the door to the fuel dump panel there are two little wooden strips on the inside of the door that when slammed closed push all of the dump switches closed. I can also confirm that the Engineers table top was wood.

Yep, that was my first thought, i remember early 747 documentaries saying that wooden planks were fitted under the tail area in case of tail end drag on the runway when taking off steeply. I also assumed it wasnt just for the 747. Having said that i often looked for something like this and could never see anything suggesting that there was wooden planks built in there.

Around 1990 ish, i was sat in the rear section of a Pan Am 747 taking off from Miami and we seemed very very late gaing airspeed and rotating, i heard a rather unusual scraping sound at that rotating point and wondered if we were on the 'planks' so to speak. It was odd that only just after leaving the ground we were immediately above the lighting posts at the end of the runway.

IF it was actually wood that was used it was only for the VMU tests. I've seen film of Boeing products actually having their tail dragged on the runway by flight test crew. Something disposable was likely used and that material never showed up in the production models.

Quoting 727forever (Reply 22):
Nope sorry. It was definately metal.

Been a while since I've been around the 727 but it seems like there was a replaceable wear plate at the lower end of the tail skid but that it might have been phenolic.

The actual compression member up inside the skid is a roll of "cardboard" wrapped very tightly and laquered into a single solid piece. It is about the size and shape of a roll of paper towels and stands on end. If the skid strikes the ground it compresses this material endwise. I've seen one shortened about half an inch by such contact but the event did many thousands of dollars in structural damage where the skid is mounted. They are not foolproof. I was told the one I was looking at came from a -100 which must be pretty hard to get a tailstrike on.

Anyway, we seem to have a winner - as usual being ignored by one and all:

I was shown the 2 pieces of wood on a Delta MD88. They were on the control columns were they go thru the cockpit floor. It is approximate horseshoe shaped and tapered near the front and approx 3/4 to 1 inch thick on the back. I wouldn't be suprised if the B727 had it there too.

The nose wheel brake consists of 2 blocks of 4X4 wood blocks in the wheel well ceiling. When the gear is retracted the tires rub against the wood blocks slowing the tire.

I've had a book since I was a kid called "747 Story of the Boeing SUPER JET" copyright 1970

Latter half of the book describes testing and early service entry.

Pg 205 talks about the VMU tests: "On its underbelly in the extreme tail is a ten foot long maple beam - like a keel on a boat - with a steel plate on the underside"

On the same page there's a pix of Jack Waddell inspecting the steel plate. I'd scan and include but I don't have my new scanner working....

On the next page an observer describes the VMU test thus: "When she rocked back on her tail, it looked like the runway was on fire. A thousand Fourth of July sparklers touched off at once!". Sounds like steel to me...

Does the 727 use wood-burning engines? 6 pieces would be hard for international flights though, I think.
