Limitations and Conditions (Continued)
This approval should not be extended to other aircraft of these models on which other previously approved modifications are incorporated, unless it is determined by the installer that the modification will introduce no adverse effect on the airworthiness of such aircraft. FAA approved high-pressure brake lines, under the meaning of this Certificate, are brake lines which the FAA has found to be sufficiently flexible for their intended purpose, compatible with MIL-H-5606BB (red) hydraulic fluid, and capable of sustaining an ultimate internal hydraulic pressure of at least 2547 PSI for at least 3 seconds without failure or leakage; and which the FAA has approved for installation on the airplane. The modification approved by this Certificate is also eligible on Piper PA-22S “150” and PA-22S “160” airplanes that have been converted to landplanes in accordance with FAA approved data.
If the holder agrees to permit another person to use this Certificate to alter the product, the holder shall give the other person written evidence of that permission.
