Why does the plane reset back to its origin? (CFrame)

Here an example: https://gyazo.com/944f3fd29f7c24dd033fa1f396b2e65d

Read below this script(this is full script)

local Crashs = math.random(1,2)

if Crashs == 1 then

local newCFrame = CFrame.Angles(math.rad(-10),0,0)
local newCFrame2 = CFrame.Angles(math.rad(10),0,0)
local TweenService = game:GetService("TweenService")
local Tweener1 = script.Parent
local Info = TweenInfo.new(2.2, Enum.EasingStyle.Linear, Enum.EasingDirection.Out, 0, false, 0)
local InfoAngle = TweenInfo.new(2.3, Enum.EasingStyle.Sine, Enum.EasingDirection.InOut, 0, false, 0 )
local Goals = { Position = Vector3.new(-16.84, -81.92, -336.77);}
local PartPositionA = TweenService:Create(Tweener1, Info, Goals)
local SecondGoals = { Position = Vector3.new(-16.84, -19.06, -3.33);}
local PartPositionB = TweenService:Create(Tweener1, Info, SecondGoals)
local ThirdGoals = { Position = Vector3.new(-18.34, -99.19, 538.82);}
local PartPositionC = TweenService:Create(Tweener1, Info, ThirdGoals)
local ForthGoals = {CFrame = Tweener1.CFrame * newCFrame }
local PartAngleA = TweenService:Create(Tweener1,InfoAngle,ForthGoals)
local FifthGoals = {CFrame = Tweener1.CFrame * newCFrame2}
local PartAngleB = TweenService:Create(Tweener1,InfoAngle,FifthGoals)


wait(2.4)
PartPositionA:play()
PartAngleA:play() --Brings back the plane FIX!
wait(1.2)
PartPositionB:play()
wait(2.2)
PartPositionC:play()
wait(1)

script.Parent.CanCollide = false


end

if Crashs == 2 then



    print ("it was 2!")




end

you really want to look at the

local ForthGoals = {CFrame = Tweener1.CFrame * newCFrame }
local PartAngleA = TweenService:Create(Tweener1,InfoAngle,ForthGoals)
local FifthGoals = {CFrame = Tweener1.CFrame * newCFrame2}
local PartAngleB = TweenService:Create(Tweener1,InfoAngle,FifthGoals)

and

wait(2.4)
PartPositionA:play()
PartAngleA:play() --Brings back the plane FIX!
wait(1.2)
PartPositionB:play()
wait(2.2)
PartPositionC:play()
wait(1)

any help is appreciated
