H-21 - Markings


My Latest And Most Expensive Manual
Correct markings are very important to the finished project

Although we have very good photos of the markings on 892, we needed the markings manual

It Doesn't Get Any Better Than This

Detailed instructions are being compared to the markings on 892 to see if they match

This Gives Us A Point By Point Reference

So far all of the 892 markings match

Look At Number 9

This was the only marking that was too broken up to identify

Using the manual we finally saw what it said

We never would have guessed it

892 Parts Organization




Most Important Parts Control Manual - The Dash 4
The Dash 4 breaks down the entire aircraft to the nut & bolt level

It is best to use this as all of the part breakdown work is done

Also, by using this information you will be acting, using the same terminology, the way people did when the aircraft was in service

This Index Provides Clarity To A Large Aircraft

There are two far more detailed indexes but this one page summary covers the entire aircraft


Finally, The Figure (In This Case No. 5) And All Included Parts
With this you get to see where the part is on the helicopter, what the part looks like and all the components that make up a usable part

Fig. 5 is the Rainshield (This is missing, if you have one a donation of the part would be appreciated)

I used this example as all the information for this part is on one page

Most parts have one or two pages for the diagram and four to six pages for the parts listing 

All of the parts control can be done on paper, however, an MS Access or Open Office database is more project friendly

892 In Viet Nam?



My Good Friend Randy Removing The Hardware In Order To Separate The Two Fuselage Halves

Over 300 U.S. ARMY CH-21C helicopters were deployed in Viet Nam between December 1961 and August 1964.

At least 19 Americans died (all U.S. ARMY personnel) on missions or in combat with the CH-21C while in Viet Nam.

Circumstantial evidence points to 892's possible service in Viet Nam between December 1961 and April 1962.

892 Did Not Want To Come Apart

892's forward fuselage has 20 skin repair patches.  Four of these (round - small) match up from bottom to top (entry - exit?) as if something ballistic passed through the helicopter

If anyone has documented information on 892 being in Viet Nam, please contact us.

H-21 - A Large Aircraft




From the Familiarization Manual

The H-21, at over 86 feet long (with rotor blades) is a large aircraft

Again from the Familiarization Manual

Here at the restoration site we do not have the rotor blades

The rotor blades (Metal, not Wood, and in good condition) are in storage at the Quonset Air Museum

The aircraft (as shown in the "892 Restoration Site" post) is in two halves and upon completion of the Nose Alighting Gear restoration (65% Done) will be reassembled here.


H-21 - Access Doors & Panels



Another Descriptive Page from the Manual Collection

This diagram shows the many Panels and Access Doors

Project 892 has most of these
