Dspice, can you start another thread on the external load issues, as I would really like to get to the bottom of the pitch up?


John, I am still asking above about the pitch up clarification if you can?

Has anybody experienced this pitch up with SPAS inoperable?

I am wondering if we might list the occurances of this pitch up that we can find out about? Remember I am talking about a pitch up that is not overcome by full forward cyclic unless collective is lowered. I am not talking about the normal ridgid rotor head reaction to tubulence bumping.

I am collecting as much info as possible on this to examine a recent occurance, and would appreciate all your info.

Occurences:

1. Australia in Dec 2005, Japanese BK117 B2. 7000 ft hp, 20 deg C. 3180 kg. 70% TQ. 120 kts IAS. SPIFR autopilot machine but being handflown in SAS mode. Turbulence present, and it ws also preceeded by a smaller pitch up bump that was controllable. Extrapolating chart VNE equals 125 kts IAS in this config.

SASless, can you fill your details in?
Hingeless, can you remember your specifics?
Oogle fire bombing speeds are generally well below VNE, particularly with bambi limits.
Blade root: have you got the specifics of the CF incident?
