The U.S. Coast Guard recognized its potential for search and rescue missions and designated it the HH-52A Seaguard, ordering 99 aircraft beginning in 1963. Powered by a General Electric T58-GE-8B turboshaft engine producing 1,250 shaft horsepower, the HH-52A could operate from both land and water, making it ideal for coastal rescue operations.\u003c\/p\u003e\n\n\u003cp\u003eThe HH-52A served as the Coast Guard's primary short-range rescue helicopter from the 1960s through the 1980s, credited with saving thousands of lives during its operational career. Its amphibious capability allowed it to land directly on water to retrieve survivors, a unique feature that proved invaluable in maritime rescue scenarios. The aircraft featured a boat-hull fuselage with retractable landing gear, enabling it to taxi on water and perform water takeoffs and landings in sea states up to four feet.\u003c\/p\u003e\n\n\u003cp\u003eProduction of the civilian S-62 and military HH-52A continued through 1967, with approximately 180 aircraft built in total. The HH-52A remained in Coast Guard service until 1989, when it was replaced by the HH-65 Dolphin. Several HH-52A aircraft have been preserved in museums, and a small number remain in private hands. The type is remembered as a workhorse of Coast Guard aviation and a pioneering design in amphibious helicopter operations.\u003c\/p\u003e\n\n\u003ch3\u003eManuals Included in This Collection\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSikorsky HH-52A Illustrated Parts Catalog Manual\u003c\/strong\u003e - CGTO 1H-52A-4 (1964)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSikorsky HH-52A Helicopter Structural Repair Manual\u003c\/strong\u003e - CGTO 1H-52-A-3 (1972)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSikorsky HH-52A Helicopter Overhaul Manual\u003c\/strong\u003e (1962)\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eSikorsky HH-52A Helicopter Training Drawings Manual\u003c\/strong\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSikorsky HH-52A Helicopter Engine Flight Handbook and Standardization Manual\u003c\/strong\u003e - CG-384-1 CGTO 1H-52A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSikorsky HH-52A Helicopter Flight Manual\u003c\/strong\u003e - T.O. 1H-52A-1\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThis collection spans the operational life of the HH-52A, from initial introduction in the early 1960s through updates in the 1970s.

Coast Guard technical orders established maintenance intervals, inspection procedures, and operational limitations specific to the maritime rescue mission. The aircraft was certificated under military standards rather than civilian FAA regulations, reflecting its dedicated government service role.\u003c\/p\u003e\n\n\u003cp\u003eSikorsky engineering practices from the 1960s emphasized robust construction for harsh maritime environments, with corrosion-resistant materials and systems designed for saltwater exposure. The amphibious boat-hull design required specialized structural engineering to withstand water landing loads while maintaining flight performance. Maintenance procedures reflected the unique requirements of amphibious operations, including hull integrity inspections, water-sealing systems, and retractable landing gear mechanisms.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePowerplant:\u003c\/strong\u003e General Electric T58-GE-8B turboshaft, 1,250 shp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotor Diameter:\u003c\/strong\u003e 53 feet (16.15 m)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e 44 feet 7 inches (13.59 m)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 13 feet 6 inches (4.11 m)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEmpty Weight:\u003c\/strong\u003e Approximately 5,600 lbs (2,540 kg)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Takeoff Weight:\u003c\/strong\u003e 8,300 lbs (3,765 kg)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCruise Speed:\u003c\/strong\u003e 98 mph (158 km\/h)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRange:\u003c\/strong\u003e 474 miles (763 km)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Ceiling:\u003c\/strong\u003e 11,200 feet (3,414 m)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrew:\u003c\/strong\u003e 2 (pilot and copilot\/rescue swimmer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e Up to 12 passengers or rescue survivors\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFormat and Delivery\u003c\/h3\u003e\n\u003cp\u003eAll manuals are delivered as high-resolution PDF files via instant digital download upon purchase.
