Well, I flew it during the civil war in Nicaragua and was wounded in one of it, during a landing when the contras taked a small village at East cost. Despite the hugh quantity of shots received in our AC and the tale transmission with damage we can flight about hundred miles an release the situation. In resume the S-58 T was my favorite one and a very wonderfull chopper.

Matt - Take a look at summithelicopters.com. They own "Screaming Mimi", the S-58T used in Rip Tide.

I used this aircraft engineer in Indonesian air force, aircraft use PT6T-6 engine. I as an engineer Sikorsky 58 T for 20 years, sadly now no longer used by the Indonesian air force. whether there is still much to use? I am very happy with this plane and the many stories along to engineer S 58 T, where the company should share the address are still using S 58 T dwi_basukir@yahoo.com this to my email.

Carlos: If you are still interested, the answer to your question is both yes and no. Yes, because the power of any engine can usually be boosted. However, this will increase wear and tear on the powerplant and bearings requiring more maintenance. The important thing to remember is that the operational ceiling of any aircraft has more to do with displacement than horsepower. That said, more displacement can be gained by replacing the main rotor with a larger or 6 bladed, lighter, more modern rotor will give you the displacement you need for high altitude operations. Be advised however, that the increased main rotor size will mean greater torque and a needed adjustment of counter-force at your collective (approximately 20% more output at tail rotor). Fuel consumption is also going to become a problem so, you may just want to get a different bird altogether.

L,

Taking a picture of a publicly owned aircraft isn't necessarily something you would 'own'. take some more pics and chill out

The limits imposed on aircraft are often limited to what is proven for FAA cerification, not necessary it's limitations.for example, The SH-60, The lardge S-53 and others are not certified to do manuvers such as rolls, loops etc but any good (Navy) helicopter pilot will tell you, they sure can.

CARLOS, e-mail, 04.06.2007reply

DEAR SIR:
I AM INTERESTED BY KNOW IF THE S-58T CAN INCREASE ITS TAKEOFF AND LANDING DENSITY ALTITUDE LIMIT TO 15,000 FEET.
IF IT IS TRULY WHAT WILL BE THE CHART OF GROSS WEIGHT VS DENSITY ALTITUDE CHART??
REGARDS
