Bell Model 230

During the autumn of 1989, Bell announced its intention to develop an improved variant of its Bell 222. Powered by two 700shp Allison 250-C30-G2 turbines driving an advanced design two-blade rotor, the Model 230 could carry up to ten people in a 3.8m3 passenger compartment. Internal fuel capacity had been increased to 930 litres with a maximum of 1359 litres with optional fuel tanks. A fixed skid undercarriage is also available and, from the 51st production aircraft, Bell will offer a variant powered by Lycoming LTS101-750 turbo-shafts. This helicopter is to be built at the company's facility in Canada. Two prototypes have been built at the Mirabel factory near Montreal and the first of these (registered C-GEXP) accomplished its maiden flight on 12 August, 1991 with certification expected during the first quarter of 1992. An initial order for twenty has been placed by Bell's Japanese representative Mitsui & Co, in Tokyo, with first deliveries due in August 1992.

Dear A/C / Helicopter Operator,

My name is Yosi and I am a retired Air Force officer specialized in aircrafts engines and logistics.

In a period of economic crisis as the world faces now, it seems to be reasonable that companies are looking for alternatives in order to reduce their expenditures; therefore, I would like to offer you my assistance as follows:
*Finding overhauls and repair facilities for your turbo shaft / turbo prop engines & modules.
*Finding engines and modules for rent or exchange.
*Finding major engine spare parts in N/F, O/H or A/R condition.
I don't charge commission from A/C owners and operators.
Please don't hesitate to contact me.
