Dave Williams Posted July 17, 2006 Share Posted July 17, 2006 (edited) A significant difference is that the cabin area on the D and later models is lot longer than the cabin on the B/C models. The fuselage is longer, the cabin is longer, the cabin doors are longer. Also, the engine housing was different. Edited July 17, 2006 by Dave Williams Quote Link to post Share on other sites
nightiemission Posted July 17, 2006 Share Posted July 17, 2006 A significant difference is that the cabin area on the D and later models is lot longer than the cabin on the B/C models. The fuselage is longer, the cabin is longer, the cabin doors are longer. Also, the engine housing was different. Also, the D model's main rotor has a longer span and wider chord. IIRC the D's was a 48' system while the B's was a 44' system. Engine also had higher SHP. HTH, Terry Quote Link to post Share on other sites
grandadjohn Posted July 17, 2006 Share Posted July 17, 2006 Late model B's, C's and D's all used the T53-L-11 engine. Early models could have had the -11 installed anytime during their service life, even in the field Quote Link to post Share on other sites
Guest Phoinix Posted July 17, 2006 Share Posted July 17, 2006 Skids are also different. A bit higher on D model. Quote Link to post Share on other sites
Sabre Posted July 17, 2006 Share Posted July 17, 2006 Dual hydraulics & 540 rotor head on B/Cs. Late model D/Hs...some had R/H tail rotor. Good to go, Jim Quote Link to post Share on other sites

Sabre Posted July 17, 2006 Share Posted July 17, 2006 I stand corrected.....the 'ol memory isn't as sharp as it once was. Thanks for catching that! Good to go, Jim Quote Link to post Share on other sites
