Cessna Citation II

1200 Pound Gross Weight Increase

The Supplemental Type Certificate (STC) described in this literature provides an increase of 1200 pounds in the useful load carried by the Citation II. This is accomplished by raising takeoff and ramp weight limitations. It offers business jet owners and pilots a cost efficient way to improve the utility of their aircraft.

Until now the Citation II has had one major drawback - with full fuel you were limited to carrying no more than one passenger. Our new STC removes this restriction by increasing the useful load of the Citation II by 1200 pounds. New Flight Corporation makes the Citation II a truly great airplane.

"Does This Compromise Performance At Lighter Weights?"


Not at all! For example, if the zero fuel weight (ZFW) for a particular flight is less than 10,000 lbs., the maximum takeoff weight for that flight is 14,500. Similarly, if the ZFW is greater than 10,000 lbs. but less than 10,500 lbs. the flight may be conducted at takeoff weights up to 14,300 lbs. Finally, for a ZFW between 10,500 and 10,950 lbs. the maximum takeoff weight is 14,100 lbs.

The approved operating weights for the three loading conditions are as follows:

  Condition A Condition B Condition C

*Equivalent Life For Aircraft With Pre-Mod Landings

Airplanes which have landings prior to the modifications have the number of pre-mod landings reduced by an equivalent post-mod life as shown in the following example:

Example
An airplane with 1000 landings recorded in its log book installs the New Flight increased ramp and takeoff modification. The nose gear assembly (P.N. 5542000-9) is now limited to 15,000 full stop landings before replacement. However, because the 1000 landings were pre-mod landings, the equivalent life is 670 landings. Each landing after the modification must be counted as a full landing, and added to the 670 total.

If the airplane had 1700 landings prior to modifications, the equivalent life would be ratioed as follows:

1139 landings would be entered in the aircraft log books in place of the 1700 landings, and each subsequent landing would be counted as a full landing. The nose gear assembly would be replaced when a total of 15,000 full stop landings was recorded.
