NOTE 7. Bell Model 47G-2 helicopters, serial numbers 1459 through 1641, 1957 through 2476, 2556 through 2559, and 2560 
through 2570 are eligible for conversion to a configuration similar to the Model 47G-2A when modified in 
accordance with Bell Service Instruction No. 384SI. Model 47G-2A Helicopter Flight Manual dated December 10, 
1960, is applicable and required with this conversion. Name Plate Requirements: The conversion plate furnished by 
Bell Helicopter Company should be permanently attached next to and just aft of the manufacturer's identification 
plate. 
 
NOTE 8. Bell Model 47G-3B.  Horsepower available corresponding to the manifold pressure of 26.8 and 31.1 listed under 
engine limits will vary with altitude with 220 and 260 horsepower as maximum, respectively. This variation is 
nonlinear. (See Lycoming Drawing 12814). Manifold pressure may be adjusted as prescribed in the Helicopter 
Flight Manual to correct for nonstandard ambient temperatures and to maintain takeoff horsepower above 10,000 
feet.  Maximum cumulative manifold pressure is 34.5 in.Hg. 
 
NOTE 9. Bell Model 47G-3B-1 with Lycoming TVO-435-B1A or -B1B engines.  Horsepower available corresponding to the 
manifold pressure of 26.8 and 32.8 in Hg. listed under engine limits will vary with altitude with 220 and 270 
horsepower as maximums, respectively. This variation is nonlinear. Manifold pressure may be adjusted as 
prescribed in the Helicopter Flight Manual to correct for nonstandard ambient temperature and to maintain takeoff 
horsepower above 8000 feet.  Maximum cumulative manifold pressure is 36.0 in.Hg. 
 
NOTE 10. Bell Model 47G-5 is a 3 PCLH (Normal Category) helicopter when Synchronized Elevator Kit P/N 47-267-485 is 
installed.  The operational limits specified in the FAA Approved Helicopter Flight Manual Supplement dated 
January 21, 1966, are applicable. See Figure 1-5 of Section I, Model 47G-5 Maintenance and Overhaul Instructions, 
for empty weight c.g. range. 
 
NOTE 11. Lycoming engine Model TVO-435-D1A is eligible in helicopter Model 47G-3B-1 when installed in accordance with 
Bell Service Instruction 411.  The following limits apply: 
Maximum continuous, 
(Sea level to 20,000) 26.6 in.Hg., 3200 r.p.m. (220 hp.) 
Takeoff (5 minutes) 
(Sea level to 5000 ft.) 32.2 in.Hg., 3200 r.p.m. (270 hp.) 
Horsepower available corresponding to the manifold pressures of 26.6 and 32.2 listed above will vary with altitude 
with 220 and 270 horsepower as maximums, respectively. This variation is nonlinear. (See Lycoming Drawing 
13023-A). Manifold pressure may be adjusted as prescribed in the Helicopter Flight Manual to correct for 
nonstandard ambient temperatures and to maintain takeoff horsepower above 5,000 feet. Maximum cumulative 
manifold pressure is 37.0 in.Hg.

NOTE 12. Bell Model 47G-3B-2 with Lycoming TVO-435-G1A engine. Horsepower available corresponding to the manifold 
pressures of 26.6 and 33.5 in.Hg. listed under engine limits will vary with altitude with 220 and 280 horsepower as 
maximums, respectively. This variation is nonlinear. Manifold pressure may be adjusted as prescribed in the 
Helicopter Flight Manual to correct for nonstandard ambient temperature and to maintain takeoff horsepower above 
4000 feet.  Maximum cumulative manifold pressure is 37.0 in.Hg. 
 
NOTE 13. Prior to civil certification, the military Model TH-13T helicopters must be modified in accordance with Bell Report 
No. 47-947-017, as revised May 27, 1968. 
 
NOTE 14. Model 47G-3B-2A helicopters equipped with the external cargo sling installed in accordance with Bell Drawing 
47-706-660 meet the structural and design requirements of the certification basis, provided the weight in excess of 
normal category gross weight is not imposed on the landing gear, when operated at 3200 pounds gross weight in 
accordance with the limits of the 47G-3B-2A FAA Approved Helicopter Flight Manual Supplement dated 
February 11, 1972, as appropriate.  The retirement times listed in NOTE 3 are not changed.
