Havilland Buffalo Specifications
DHC-5/CV-7A:
4 produced and delivered to the U. S. Army. Two of these served
for a trial period in Vietnam
DHC-5A: 55 produced - Canadian Forces (15), Brazilian
Air Force (24), Peruvian Air Force (16)
DHC-5B: A proposed version using the G.E. T64-P4C engine
(never produced)
DHC-5C: A proposed version for the Indian Air Force
using the R.R. Dart 12 engine (never produced)
DHC-5D: The last production version (S/N 60 and
subsequent)
The -5D
introduced the concept of higher operating weights and increased
payload when operating in a "Transport" role (firm, smooth
runways, 2.5g maneuver load factor, restricted flap settings, 10
ft/second limit rate of descent at landing touchdown) in
addition to the "Assault" role capabilities of the earlier
versions.
"Beta"
propellers were introduced on S/N 79 and are standard on
subsequent aircraft.
