1. Chapter 2 Development of Maintenance Programs
Introduction
World War II involved specialized aircraft produced in large numbers by various combatant nations, and many makes of familiar names domestically became known internationally.
WWI spurred acft production, the acft were not available in the beginning of the war.
There were many efforts to prevent war, but the militaristic goals of a few countries pulled other countries into conflict.
WWII was worldwide with concentrations of fighting in Europe and the Pacific.
Hitler wanted to acquired more living space which he tried to do by taking starting war with other countries.

3. Process-oriented 3 primary processes Hard time (HT)

Not eligible for condition monitoring
Definite life limits
Detectable wear-out periods
Adverse affect on safety
Removed/overhauled/discarded before exceeding specified interval
Structural inspection
Landing gear overhaul
Life-limited engine parts
Poland Falls: The German invasion of Poland began on 1 September 1939, concluded with Poland’s surrender a month later, and demonstrated Germany’s use of aircraft to destroy a country’s air combat capabilities early during an assault — a tactic Germany used repeatedly in its effort to make Europe German by capturing countries one by one. Blitzkrieg – lightning war, fast moving assaults using infantry and tanks supported by acft.
The Phony War: The winter of provided a lull in the fighting and grounded many aircraft.
Winter War: The Soviet invasion of Finland and the subsequent Winter War between two neighbors of vastly different sizes demonstrated that attrition of a combatant’s resources, not absolute numbers of wins and losses, could determine the outcome of combat. WX restricted aerial operations. The Polish army was not prepared to fight.
The Battle for France: Belgium and Holland were in Germany’s way around the northwestern end of France’s fortified Maginot Line, so the German Luftwaffe (Air Force) bombed Belgium and Dutch as well as French airfields and planes on the ground and German pilots fought particularly French and British aircraft in the air.
Dunkirk: Pushed to the sea (the English Channel) by advancing German forces, the British Expeditionary Force and France’s Northern Army evacuated 300,000 men from Dunkirk to the safety of England across the channel — under the aerial protection of British Spitfires and other fighter planes. Germany won the battle over Dunkirk in terms of fighter stats. Germany flew 2,000 sorties and lost 37 acft, British flew 1,764 sorties & lost 106 acft.
Mediterranean Region: Concurrent with the Battle for France, Germany launched a major paratroop attack against Crete, and Italy joined Germany in the fighting to conquer enemy lands in the Mediterranean region.
French Governments: After the fall of France in June 1942, the French government became scattered governments: There was German-ruled “occupied France,” and south of that was authoritarian “Vichy France,” and throughout France there was a “resistance” movement, also south of the Mediterranean Sea were “Free French” colonies in Africa led by General Charles de Gualle who was in exile in Great Britain.
Battle of Britain: The Battle of Britain was an air battle preliminary to a German invasion that never happened because the Royal Air Force escaped destruction on the ground and fought an effective defensive battle against Luftwaffe bombers, fighters, and blitz tactics. Britain had radar to guide airplanes from the ground.
Battle of the Atlantic: The maritime battle of the Atlantic employed aircraft in reconnaissance, fighter, torpedo bomber, and other roles.
Sortie – one mission by a single military plane.
The German Luftwaffe was one of the most powerful, doctrinally advanced, and battle experienced air forces in the world when WWII started.

The Battle for France: Belgium and Holland were in Germany’s way around the northwestern end of France’s fortified Maginot Line, so the German Luftwaffe (Air Force) bombed Belgium and Dutch as well as French airfields and planes on the ground and German pilots fought particularly French and British aircraft in the air.
Dunkirk: Pushed to the sea (the English Channel) by advancing German forces, the British Expeditionary Force and France’s Northern Army evacuated 300,000 men from Dunkirk to the safety of England across the channel — under the aerial protection of British Spitfires and other fighter planes. Germany won the battle over Dunkirk in terms of fighter stats. Germany flew 2,000 sorties and lost 37 acft, British flew 1,764 sorties & lost 106 acft.
Mediterranean Region: Concurrent with the Battle for France, Germany launched a major paratroop attack against Crete, and Italy joined Germany in the fighting to conquer enemy lands in the Mediterranean region.
French Governments: After the fall of France in June 1942, the French government became scattered governments: There was German-ruled “occupied France,” and south of that was authoritarian “Vichy France,” and throughout France there was a “resistance” movement, also south of the Mediterranean Sea were “Free French” colonies in Africa led by General Charles de Gualle who was in exile in Great Britain.
Battle of Britain: The Battle of Britain was an air battle preliminary to a German invasion that never happened because the Royal Air Force escaped destruction on the ground and fought an effective defensive battle against Luftwaffe bombers, fighters, and blitz tactics. Britain had radar to guide airplanes from the ground.
Battle of the Atlantic: The maritime battle of the Atlantic employed aircraft in reconnaissance, fighter, torpedo bomber, and other roles.

Poland Falls: The German invasion of Poland began on 1 September 1939, concluded with Poland’s surrender a month later, and demonstrated Germany’s use of aircraft to destroy a country’s air combat capabilities early during an assault — a tactic Germany used repeatedly in its effort to make Europe German by capturing countries one by one.
