What was found
REPAIR STATION IS HOLDER OF STC SA03674AT FOR THE INSTALATION OF R-134 COOLANT AIR CONDITIONER SYS IN THIS ACFT. IAW THIS STC INSTALLATION, A CONDENSER HOUSING IS MOUNTED ON THE BOTTOM OF THE ACFT FUSELAGE. IT HAS BEEN DISCOVERED THAT THE SCREEN WHICH COVERS THE FRONT OF THE CONDENSER HSG HAS CRACKED WHERE IT ATTACHES TO THE CONDENSER HSG. PROBABLE CAUSE OF THIS CONDITION IS VIBRATION. A MORE STURDY SCREEN ATTAHMENT SYS IS BEING INVESTIGATED TO CORRECT THE PROBLEM. THE CRACKING OF THIS SCREEN DOES NOT AFFECT THE AIRWORTHINESS OF THE ACFT NOR DOES IT AFFECT THE OPERATION OF THE AIR CONDITIONING SYS OR THE ACFT IN GENERAL. (K)
