Tie down ratings 212 / S61
 

Hi:
Sorry for posting on such a boring subject;

Does anyone happen to have the vertical, fore, aft and lateral limits for the cargo tiedowns on the Bell 205/212/412 series and also the S-61.

I would like to know both the limits on the tiedowns themselves and the floor fittings. How many "G" at max weight are the fittings designed for - that sort of stuff.


No earth shattering need just it came up in discussion about installing things such as Ferry tanks or survey equipment on a temp basis and inquiring minds would like to know.

A reference to the info would be nice.

Nick??? Got any good stuff?

Thanks.

The max G loading determined by the FARs that the aircraft were designed to will determine the max load in pounds per tie-down.

The max load per tie-down should be in the Maintenance Manual and the Flight Manual.

From the Bell 212 Flight Manual:

Deck mounted ..... 1250lbs vertical and 500lbs horizontal per fitting.
Bulkhead mounted.....1250lbs at 90deg to the bulkhead and 500lbs in any direction parallel to the bulkhead.

I can't find any reference in my S61 training notes, but I seem to recall that they are fairly similar to the 212.

Thanks John and TRC:

I don't have access to the RFM / MM at the moment.

I seem to remember that the 212/412 floor tie-downs also have a rating of 1350lbs at 22 degrees from the verticle. which is great if you have the protractor handy when loading:ok:

methinks this comes from the sum of the two vectors, certainly thats how the maths works, how usefull it is is another matter :confused:
